        3-D Liver Segmentation Method with Parallel Computing for Selective Internal Radiation
6201
        Therapy

        This study describes a new 3-D liver segmentation method in support of the selective internal radiation treatment as a
        treatment for liver tumors. This 3-D segmentation is based on coupling a modified k-means segmentation method with a
        special localized contouring algorithm. In the segmentation process, five separate regions are identified on the
        computerized tomography image frames. The merit of the proposed method lays in its potential to provide fast and
        accurate liver segmentation and 3-D rendering as well as in delineating tumor region(s), all with minimal user interaction.
        Leveraging of multicore platforms is shown to speed up the processing of medical images considerably, making this
        method more suitable in clinical settings. Experiments were performed to assess the effect of parallelization using up to
        442 slices. Empirical results, using a single workstation, show a reduction in processing time from 4.5 h to almost 1 h for
        a 78% gain. Most important is the accuracy achieved in estimating the volumes of the liver and tumor region(s), yielding
        an average error of less than 2% in volume estimation over volumes generated on the basis of the current manually
        guided segmentation processes. Results were assessed using the analysis of variance statistical analysis.

 EGC     A New Intelligence-Based Approach for Computer-Aided Diagnosis of Dengue Fever
 6202



         Identification of the influential clinical symptoms and laboratory features that help in the diagnosis of dengue fever (DF)
        in early phase of the illness would aid in designing effective public health management and virological surveillance
        strategies. Keeping this as our main objective, we develop in this paper a new computational intelligence-based
        methodology that predicts the diagnosis in real time, minimizing the number of false positives and false negatives. Our
        methodology consists of three major components: 1) a novel missing value imputation procedure that can be applied on
        any dataset consisting of categorical (nominal) and/or numeric (real or integer); 2) a wrapper-based feature selection
        method with genetic search for extracting a subset of most influential symptoms that can diagnose the illness; and 3) an
        alternating decision tree method that employs boosting for generating highly accurate decision rules. The predictive
        models developed using our methodology are found to be more accurate than the state-of-the-art methodologies used in
        the diagnosis of the DF.


EGC     A Novel Semi-automated Atherosclerotic Plaque Characterization Method Using Grayscale

        Intravascular Ultrasound Images: Comparison With Virtual Histology

        Intravascular ultrasound (IVUS) virtual histology (VH-IVUS) is a new technique, which provides automated plaque
        characterization in IVUS frames, using the ultrasound backscattered RF-signals. However, its computation can only be

         performed once per cardiac cycle (ECG-gated technique), which significantly decreases the number of characterized
         IVUS frames. Also atherosclerotic plaques in images that have been acquired by machines, which are not equipped with
         the VH software, cannot be characterized. To address these limitations, we have developed a plaque characterization
         technique that can be applied in grayscale IVUS images. Our semiautomated method is based on a three-step approach.
         In the first step, the plaque area [region of interest (ROI)] is detected semiautomatically. In the second step, a set of
         features is extracted for each pixel of the ROI and in the third step, a random forest classifier is used to classify these
         pixels into four classes: dense calcium, necrotic core, fibrotic tissue, and fibro-fatty tissue. In order to train and validate
         our method, we used 300 IVUS frames acquired from virtual histology examinations from ten patients. The overall
         accuracy of the proposed method was 85.65% suggesting that our approach is reliable and may be further investigated
         in the clinical and research arena.



  EGC       A Reliable Transmission Protocol for ZigBee-Based Wireless Patient Monitoring
  6204



         Patient monitoring systems are gaining their importance as the fast-growing global elderly population increases
         demands for caretaking. These systems use wireless technologies to transmit vital signs for medical evaluation. In a
         multihop ZigBee network, the existing systems usually use broadcast or multicast schemes to increase the reliability of
         signals transmission; however, both the schemes lead to significantly higher network traffic and end-to-end
         transmission delay. In this paper, we present a reliable transmission protocol based on anycast routing for wireless
         patient monitoring. Our scheme automatically selects the closest data receiver in an anycast group as a destination to
         reduce the transmission latency as well as the control overhead. The new protocol also shortens the latency of path
         recovery by initiating route recovery from the intermediate routers of the original path. On the basis of a reliable
         transmission scheme, we implement a ZigBee device for fall monitoring, which integrates fall detection, indoor
         positioning, and ECG monitoring. When the triaxial accelerometer of the device detects a fall, the current position of the
         patient is transmitted to an emergency center through a ZigBee network. In order to clarify the situation of the fallen
         patient, 4-s ECG signals are also transmitted. Our transmission scheme ensures the successful transmission of these
         critical messages. The experimental results show that our scheme is fast and reliable. We also demonstrate that our
         devices can seamlessly integrate with the next generation technology of wireless wide area network, worldwide
         interoperability for microwave access, to achieve real-time patient monitoring.

6205      A RESTful Image Gateway for Multiple Medical Image Repositories


          Mobile technologies are increasingly important components in telemedicine systems and are becoming powerful
          decision support tools. Universal access to data may already be achieved by resorting to the latest generation of tablet
          devices and smartphones. However, the protocols employed for communicating with image repositories are not suited
          to exchange data with mobile devices. In this paper, we present an extensible approach to solving the problem of

         describe a three-tiered component-based gateway that acts as an intermediary between medical applications and a
         number of Picture Archiving and Communication Systems (PACS). The interface with the gateway is accomplished
         using Hypertext Transfer Protocol (HTTP) requests following a Representational State Transfer (REST) methodology,
         which relieves developers from dealing with complex medical imaging protocols and allows the processing of data on
         the server side.

 EGC
          A Review on Digital ECG Formats and the Relationships Between Them
 6206


         A plethora of digital ECG formats have been proposed and implemented. This heterogeneity hinders the design and
        development of interoperable systems and entails critical integration issues for the healthcare information systems. This
        paper aims at performing a comprehensive overview on the current state of affairs of the interoperable exchange of
        digital ECG signals. This includes 1) a review on existing digital ECG formats, 2) a collection of applications and
        cardiology settings using such formats, 3) a compilation of the relationships between such formats, and 4) a reflection
        on the current situation and foreseeable future of the interoperable exchange of digital ECG signals. The objectives have
        been approached by completing and updating previous reviews on the topic through appropriate database mining. 39
        digital ECG formats, 56 applications, tools or implantation experiences, 47 mappings/converters, and 6 relationships
        between such formats have been found in the literature. The creation and generalization of a single standardized ECG
        format is a desirable goal. However, this unification requires political commitment and international cooperation among
        different standardization bodies. Ongoing ontology-based approaches covering ECG domain have recently emerged as
        a promising alternative for reaching fully fledged ECG interoperability in the near future.


EGC      A Smart Health Monitoring Chair for Nonintrusive Measurement of Biological Signals
6207


        We developed nonintrusive methods for simultaneous electrocardiogram, photoplethysmogram, and ballistocardiogram
        measurements that do not require direct contact between instruments and bare skin. These methods were applied to the
        design of a diagnostic chair for unconstrained heart rate and blood pressure monitoring purposes. Our methods were
        operationalized through capacitively coupled electrodes installed in the chair back that include high-input impedance
        amplifiers, and conductive textiles installed in the seat for capacitive driven-right-leg circuit configuration that is capable
        of recording electrocardiogram information through clothing. Photoplethysmograms were measured through clothing
        using seat mounted sensors with specially designed amplifier circuits that vary in light intensity according to clothing
        type. Ballistocardiograms were recorded using a film type transducer material, polyvinylidenefluoride (PVDF), which was
        installed beneath the seat cover. By simultaneously measuring signals, beat-to-beat heart rates could be monitored even
        when electrocardiograms were not recorded due to movement artifacts. Beat-to-beat blood pressure was also monitored
        using unconstrained measurements of pulse arrival time and other physiological parameters, and our experimental
        results indicated that the estimated blood pressure tended to coincide with actual blood pressure measurements. This

  EGC      Abnormality Segmentation in Brain Images Via Distributed Estimation
  6208


         The aim of this paper is to introduce a novel semisupervised scheme for abnormality detection and segmentation in
         medical images. Semisupervised learning does not require pathology modeling and, thus, allows high degree of
         automation. In abnormality detection, a vector is characterized as anomalous if it does not comply with the probability
         distribution obtained from normal data. The estimation of the probability density function, however, is usually not
         feasible due to large data dimensionality. In order to overcome this challenge, we treat every image as a network of
         locally coherent image partitions (overlapping blocks). We formulate and maximize a strictly concave likelihood function
         estimating abnormality for each partition and fuse the local estimates into a globally optimal estimate that satisfies the
         consistency constraints, based on a distributed estimation algorithm. The likelihood function consists of a model and a
         data term and is formulated as a quadratic programming problem. The method is applied for automatically segmenting
         brain pathologies, such as simulated brain infarction and dysplasia, as well as real lesions in diabetes patients. The
         assessment of the method using receiver operating characteristic analysis demonstrates improvement in image
         segmentation over two-group analysis performed with Statistical Parametric Mapping (SPM).

6209      An Info button For Web 2.0 Clinical Discussions:The Knowledge Linkage Framework


         This paper aims to develop an infobutton to automatically retrieve published papers corresponding to a topic-specific
         online clinical discussion. The knowledge linkages infobutton is designed to supplement online clinical conversations
         with pertinent medical literature from Pubmed. The project involves three distinct steps: 1) Clinical messages around a
         specific problem are grouped together into a thread. 2) These threads are processed using Metamap to link the
         conversations to keywords from the MeSH lexicon. 3) These keywords are used in a novel search strategy to retrieve a
         set of papers from Pubmed, which are then returned to the user. A pilot study using the messages from 2007 and 2008,
         was conducted to compare the knowledge linkage search strategy to a vector space model and extended Boolean
         model. The knowledge linkage model proved to be significantly better in terms of precision (p = 0.013 and 0.003,
         respectively) and recall (p = 0.351 and 0.013). Pertinent papers were returned to over 55% of the threads. This approach
         has demonstrated how clinicians can supplement their peer communications with evidence based research. Future work
         should focus on how to improve the threading and keyword-mapping strategies.

       Wireless body sensor network (WBSN), a key building block for m-Health, demands extremely stringent resource
       constraints and thus lightweight security methods are preferred. To minimize resource consumption, utilizing
       information already available to a WBSN, particularly common to different sensor nodes of a WBSN, for security
       purposes becomes an attractive solution. In this paper, we tested the randomness and distinctiveness of the 128-bit
       biometric binary sequences (BSs) generated from interpulse intervals (IPIs) of 20 healthy subjects as well as 30 patients
       suffered from myocardial infarction and 34 subjects with other cardiovascular diseases. The encoding time of a
       biometric BS on a WBSN node is on average 23 ms and memory occupation is 204 bytes for any given IPI sequence. The
       results from five U.S. National Institute of Standards and Technology statistical tests suggest that random biometric BSs
       can be generated from both healthy subjects and cardiovascular patients and can potentially be used as authentication
       identifiers for securing WBSNs. Ultimately, it is preferred that these biometric BSs can be used as encryption keys such
       that key distribution over the WBSN can be avoided.



EGC      Anonymization of Longitudinal Electronic Medical Records
6211


       Electronic medical record (EMR) systems have enabled healthcare providers to collect detailed patient information from
       the primary care domain. At the same time, longitudinal data from EMRs are increasingly combined with biorepositories
       to generate personalized clinical decision support protocols. Emerging policies encourage investigators to disseminate
       such data in a deidentified form for reuse and collaboration, but organizations are hesitant to do so because they fear
       such actions will jeopardize patient privacy. In particular, there are concerns that residual demographic and clinical
       features could be exploited for reidentification purposes. Various approaches have been developed to anonymize
       clinical data, but they neglect temporal information and are, thus, insufficient for emerging biomedical research
       paradigms. This paper proposes a novel approach to share patient-specific longitudinal data that offers robust privacy
       guarantees, while preserving data utility for many biomedical investigations. Our approach aggregates temporal and
       diagnostic information using heuristics inspired from sequence alignment and clustering methods. We demonstrate that
       the proposed approach can generate anonymized data that permit effective biomedical analysis using several patient
       cohorts derived from the EMR system of the Vanderbilt University Medical Center.

         Application of Evolutionary Fuzzy Cognitive Mapsfor Prediction of Pulmonary
         Infections
       In this paper, a new evolutionary-based fuzzy cognitive map (FCM) methodology is proposed to cope with the
       forecasting of the patient states in the case of pulmonary infections. The goal of the research was to improve the
       efficiency of the prediction. This was succeeded with a new data fuzzification procedure for observables and
       optimization of gain of transformation function using the evolutionary learning for the construction of FCM model. The
       approach proposed in this paper was validated using real patient data from internal care unit. The results emerged had
       less prediction errors for the examined data records than those produced by the conventional genetic-based algorithmic
       approaches.

EGC     Artifact Removal in Physiological Signals—Practices and Possibilities
6213


       The combination of reducing birth rate and increasing life expectancy continues to drive the demographic shift toward
       an aging population. This, in turn, places an ever-increasing burden on healthcare due to the increasing prevalence of
       patients with chronic illnesses and the reducing income-generating population base needed to sustain them. The need
       to urgently address this healthcare “time bomb” has accelerated the growth in ubiquitous, pervasive, distributed
       healthcare technologies. The current move from hospital-centric healthcare toward in-home health assessment is aimed
       at alleviating the burden on healthcare professionals, the health care system and caregivers. This shift will also further
       increase the comfort for the patient. Advances in signal acquisition, data storage and communication provide for the
       collection of reliable and useful in-home physiological data. Artifacts, arising from environmental, experimental and
       physiological factors, degrade signal quality and render the affected part of the signal useless. The magnitude and
       frequency of these artifacts significantly increases when data collection is moved from the clinic into the home. Signal
       processing advances have brought about significant improvement in artifact removal over the past few years. This paper
       reviews the physiological signals most likely to be recorded in the home, documenting the artifacts which occur most
       frequently and which have the largest degrading effect. A detailed analysis of current artifact removal techniques will
       then be presented. An evaluation of the advantages and disadvantages of each of the proposed artifact detection and
       removal techniques, with particular application to the personal healthcare domain, is provided.

       Developmentin the Arteries

       Despite Atherosclerosis is a progressive disease characterized by the accumulation of lipids and fibrous elements in
       arteries. It is characterized by dysfunction of endothelium and vasculitis, and accumulation of lipid, cholesterol, and cell
       elements inside blood vessel wall. In this study, a continuum-based approach for plaque formation and development in
       3-D is presented. The blood flow is simulated by the 3-D Navier-Stokes equations, together with the continuity equation
       while low-density lipoprotein (LDL) transport in lumen of the vessel is coupled with Kedem-Katchalsky equations. The
       inflammatory process was solved using three additional reaction-diffusion partial differential equations. Transport of
       labeled LDL was fitted with our experiment on the rabbit animal model. Matching with histological data for LDL
       localization was achieved. Also, 3-D model of the straight artery with initial mild constriction of 30% plaque for formation
       and development is presented.

        very intense activities. This evaluation methodology demonstrated to be effective for the definition of the limits of use of
        wearable sensors. Furthermore, the ProeTEX prototype demonstrated to be reliable, since it produced negligible errors

 EGC      Assessment of Tremor Activity in the Parkinson’sDisease Using a Set of Wearable
 6216
          Sensors

        Tremor is the most common motor disorder of Parkinson's disease (PD) and consequently its detection plays a crucial
        role in the management and treatment of PD patients. The current diagnosis procedure is based on subject-dependent
        clinical assessment, which has a difficulty in capturing subtle tremor features. In this paper, an automated method for
        both resting and action/postural tremor assessment is proposed using a set of accelerometers mounted on different
        patient's body segments. The estimation of tremor type (resting/action postural) and severity is based on features
        extracted from the acquired signals and hidden Markov models. The method is evaluated using data collected from 23
        subjects (18 PD patients and 5 control subjects). The obtained results verified that the proposed method successfully: 1)
        quantifies tremor severity with 87 % accuracy, 2) discriminates resting from postural tremor, and 3) discriminates tremor
        from other Parkinsonian motor symptoms during daily activities.

        Automated Recognition of Obstructive Sleep ApneaSyndrome Using Support Vector
6217
        Machine Classifier

        Obstructive sleep apnea (OSA) is a common sleep disorder that causes pauses of breathing due to repetitive
        obstruction of the upper airways of the respiratory system. The effect of this phenomenon can be observed in other
        physiological signals like the heart rate variability, oxygen saturation, and the respiratory effort signals. In this study,
        features from these signals were extracted from 50 control and 50 OSA patients from the Sleep Heart Health Study
        database and implemented for minute and subject classifications. A support vector machine (SVM) classifier was used
        with linear and second-order polynomial kernels. For the minute classification, the respiratory features had the highest
        sensitivity while the oxygen saturation gave the highest specificity. The polynomial kernel always had better
        performance and the highest accuracy of 82.4% (Sen: 69.9%, Spec: 91.4%) was achieved using the combined-feature
        classifier. For subject classification, the polynomial kernel had a clear improvement in the oxygen saturation accuracy

       as the highest accuracy of 95% was achieved by both the oxygen saturation (Sen: 100%, Spec: 90.2%) and the
       combined-feature (Sen: 91.8%, Spec: 98.0%). Further analysis of the SVM with other kernel types might be useful for
       optimizing the classifier with the appropriate features for an OSA automated detection algorithm.

EGC    Cardiovascular Modeling of Congenital Heart Disease Based on Neonatal Echo
6218
       cardiographic Images

       This paper proposes a 3-D cardiovascular modeling system based on neonatal echocardiographic images. With the
       system, medical doctors can interactively construct patient-specific cardiovascular models, and share the complex
       topology and the shape information. For the construction of cardiovascular models with a variety of congenital heart
       diseases, we propose a set of algorithms and interface that enable editing of the topology and shape of the 3-D models.
       In order to facilitate interactivity, the centerline and radius of the vessels are used to edit the surface of the heart
       vessels. This forms a skeleton where the centerlines of blood vessel serve as the nodes and edges, while the radius of
       the blood vessel is given as an attribute value to each node. Moreover, parent-child relationships are given to each
       skeleton. They are expressed as the directed acyclic graph, where the skeletons are viewed as graph nodes and the
       connecting points are graph edges. The cardiovascular models generated from some patient data confirmed that the
       developed technique is capable of constructing cardiovascular disease models in a tolerable timeframe. It is successful
       in representing the important structures of the patient-specific heart vessels for better understanding in preoperative
       planning and electric medical recording of the congenital heart disease



EGC    Compensation of Sound Speed Deviations in3-D B-Mode Ultrasound for Intraoperative

       Determination of the Anterior Pelvic Plane

       An accurate determination of the pelvic orientation is inevitable for the correct cup prosthesis placement of navigated
       total hip arthroplasties. Conventionally, this step is accomplished by percutaneous palpation of anatomic landmarks.
       Sterility issues and an increased landmark localization error for obese patients lead to the application of B-mode
       ultrasound imaging in the field of computer-assisted orthopedic surgery. Many approaches have been proposed in the
       literature to replace the percutaneous digitization by 3-D B-mode ultrasound imaging. However, the correct depth
       localization of the pelvic landmarks could be significantly affected by the acoustic properties of the penetrated tissues.
       Imprecise depth estimation could lead to a miscalculation of the pelvic orientation and subsequently to a misalignment
       of the acetabular cup implant. But so far, no solution has been presented, which compensates for acoustic property
       differences for correct depth estimation. In this paper, we present a novel approach to determine pelvic orientation from
       ultrasound images by applying a hierarchical registration scheme based on patch statistical shape models to
       compensate for differences in speed of sound. The method was validated based on plastic bones and a cadaveric
       specimen.

       Context-Based Electronic Health Record: TowardPatient Specific Healthcare
6220


       Due to the increasingly data-intensive clinical environment, physicians now have unprecedented access to detailed
       clinical information from a multitude of sources. However, applying this information to guide medical decisions for a
       specific patient case remains challenging. One issue is related to presenting information to the practitioner: displaying a
       large (irrelevant) amount of information often leads to information overload. Next-generation interfaces for the electronic
       health record (EHR) should not only make patient data easily searchable and accessible, but also synthesize fragments
       of evidence documented in the entire record to understand the etiology of a disease and its clinical manifestation in
       individual patients. In this paper, we describe our efforts toward creating a context-based EHR, which employs
       biomedical ontologies and (graphical) disease models as sources of domain knowledge to identify relevant parts of the
       record to display. We hypothesize that knowledge (e.g., variables, relationships) from these sources can be used to
       standardize, annotate, and contextualize information from the patient record, improving access to relevant parts of the
       record and informing medical decision making. To achieve this goal, we describe a framework that aggregates and
       extracts findings and attributes from free-text clinical reports, maps findings to concepts in available knowledge
       sources, and generates a tailored presentation of the record based on the information needs of the user. We have
       implemented this framework in a system called Adaptive EHR, demonstrating its capabilities to present and synthesize
       information from neurooncology patients. This paper highlights the challenges and potential applications of leveraging
       disease models to improve the access, integration, and interpretation of clinical patient data.



EGC    Contextualized Access to Electronical HealthRecords in Cardiology
6220


       In this paper, we propose a new approach for accessing the electronical health records (EHR), and we apply it to the
       cardiology medical specialty. Though the use of EHR improves the storage and access to the information in it regarding
       the previous health records in papers, it entails the risk of having the same problems of huge size and of becoming
       inoperative and really difficult to handle, especially if the user is looking for a specific data item. Our proposal is based
       on the contextualization of the access, providing the user with the most important information for the assistance act in
       which he/she is involved. To do this, we define the set of possible contexts and consider different aspects of the
       pertinence of the documents to each context. We do it by using fuzzy logic and pay special attention to the efficiency,
       due to the huge size of the involved databases. Our proposal does not limit the access to the EHR, but establishes a
       prioritization based on the access needs, which provides the system with an additional advantage, easily enabling the
       use of new terminals and devices like tablet PCs and PDAs, which have great limitations in the interfaces.

       It is well known that the evolution of 4G-based mobile multimedia network systems will contribute significantly to future
       mobile healthcare (m-health) applications that require high bandwidth and fast data rates. Central to the success of such
       emerging applications is the compatibility of broadband networks, such as mobile Worldwide Interoperability For
       Microwave Access (WiMAX) and High-Speed Uplink Packet Access (HSUPA), and especially their rate adaption issues
       combined with the acceptable real-time medical quality of service requirements. In this paper, we address the relevant
       challenges of cross-layer design requirements for real-time rate adaptation of ultrasound video streaming in mobile
       WiMAX and HSUPA networks. A comparative performance analysis of such approach is validated in two experimental m-
       health test bed systems for both mobile WiMAX and HSUPA networks. The experimental results have shown an
       improved performance of mobile WiMAX compared to the HSUPA using the same cross-layer optimization approach.

       Utilization of information and communication technologies such as mobile phones and wireless sensor networks
       becomes more and more common in the field of telemonitoring for chronic diseases. Providing elderly people with a
       mobile-phone-based patient terminal requires a barrier-free design of the overall user interface including the setup of
       wireless communication links to sensor devices. To easily manage the connection between a mobile phone and wireless
       sensor devices, a concept based on the combination of Bluetooth and near-field communication technology has been
       developed. It allows us initiating communication between two devices just by bringing them close together for a few
       seconds without manually configuring the communication link. This concept has been piloted with a sensor device and
       evaluated in terms of usability and feasibility. Results indicate that this solution has the potential to simplify the
       handling of wireless sensor networks for people with limited technical skills.


EGC     Detection and Analysis of Transitional Activity in Manifold Space
6223



       Activity monitoring is important for assessing daily living conditions for elderly patients and those with chronic
       diseases. Transitions between activities can present characteristic patterns that may be indicative of quality of
       movement. To detect and analyze transitional activities, a manifold-based approach is proposed in this paper. The
       proposed method uses a recursive spectral graph-partitioning algorithm to segment transitions in activity. These
       segments are subsequently mapped to a reference manifold space. Categorization of transitions is performed with the
       corresponding features in the manifold space. The practical value of the work is demonstrated through data collected
       under laboratory conditions, as well as patients recovering from total knee replacement operations, demonstrating
       specific transitions and motion impairment compared to normal subjects.

        Development and Evaluation of an Ambulatory Stress Monitor Based on Wearable
        Sensors

       Chronic stress is endemic to modern society. However, as it is unfeasible for physicians to continuously monitor stress
       levels, its diagnosis is nontrivial. Wireless body sensor networks offer opportunities to ubiquitously detect and monitor
       mental stress levels, enabling improved diagnosis, and early treatment. This article describes the development of a
       wearable sensor platform to monitor a number of physiological correlates of mental stress. We discuss tradeoffs in both
       system design and sensor selection to balance information content and wearability. Using experimental signals
       collected from the wearable sensor, we describe a selected number of physiological features that show good correlation
       with mental stress. In particular, we propose a new spectral feature that estimates the balance of the autonomic nervous
       system by combining information from the power spectral density of respiration and heart rate variability. We validate
       the effectiveness of our approach on a binary discrimination problem when subjects are placed under two
       psychophysiological conditions: mental stress and relaxation. When used in a logistic regression model, our feature set
       is able to discriminate between these two mental states with a success rate of 81% across subjects.

       This paper presents the latest progress made concerning a hybrid diagnostic and therapeutic system able to provide
       focused microwave radiometric temperature and/or conductivity variation measurements and hyperthermia treatment.
       Previous experimental studies of our group have demonstrated the system performance and focusing properties in
       phantom as well as human experiments. The system is able to detect temperature and conductivity variations with
       frequency-dependent detection depth and spatial sensitivity. Numerous studies have also demonstrated the
       improvement of the system focusing properties attributed to the use of dielectric and left handed matching layers. In this
       study, similar experimental procedures are performed but this time using an anatomical head model as phantom aiming
       to achieve a more accurate modeling of the system's future real function. This way, another step is made toward the
       deeper understanding of the system's capabilities, with the view to further use it in experimental procedures with
       laboratory animals and human volunteers.

        Fuzzy Local Gaussian Mixture Model for Brain MR Image Segmentation
6227



        Accurate brain tissue segmentation from magnetic resonance (MR) images is an essential step in quantitative brain
        image analysis. However, due to the existence of noise and intensity inhomogeneity in brain MR images, many
        segmentation algorithms suffer from limited accuracy. In this paper, we assume that the local image data within each
        voxel's neighborhood satisfy the Gaussian mixture model (GMM), and thus propose the fuzzy local GMM (FLGMM)
        algorithm for automated brain MR image segmentation. This algorithm estimates the segmentation result that maximizes
        the posterior probability by minimizing an objective energy function, in which a truncated Gaussian kernel function is
        used to impose the spatial constraint and fuzzy memberships are employed to balance the contribution of each GMM.
        We compared our algorithm to state-of-the-art segmentation approaches in both synthetic and clinical data. Our results
        show that the proposed algorithm can largely overcome the difficulties raised by noise, low contrast, and bias field, and
        substantially improve the accuracy of brain MR image segmentation.

        HBS: A Novel Biometric Feature Based on Heartbeat Morphology
6228



        In this paper, a new feature named heartbeat shape (HBS) is proposed for ECG-based biometrics. HBS is computed from
        the morphology of segmented heartbeats. Computation of the feature involves three basic steps: 1) resampling and
        normalization of a heartbeat; 2) reduction of matching error; and 3) shift invariant transformation. In order to construct
        both gallery and probe templates, a few consecutive heartbeats which could be captured in a reasonably short period of
        time are required. Thus, the identification and verification methods become efficient. We have tested the proposed
        feature independently on two publicly available databases with 76 and 26 subjects, respectively, for identification and
        verification. The second database contains several subjects having clinically proven cardiac irregularities (atrial
        premature contraction arrhythmia). Experiments on these two databases yielded high identification accuracy (98% and
        99.85%, respectively) and low verification equal error rate (1.88% and 0.38%, respectively). These results were obtained
        by using templates constructed from five consecutive heartbeats only. This feature compresses the original ECG signal
        significantly to be useful for efficient communication and access of information in telecardiology scenarios.

        Glioma, especially glioblastoma, is a leading cause of brain cancer fatality involving highly invasive and neoplastic
        growth. Diffusive models of glioma growth use variations of the diffusion-reaction equation in order to simulate the
        invasive patterns of glioma cells by approximating the spatiotemporal change of glioma cell concentration. The most
        advanced diffusive models take into consideration the heterogeneous velocity of glioma in gray and white matter, by
        using two different discrete diffusion coefficients in these areas. Moreover, by using diffusion tensor imaging (DTI), they

        simulate the anisotropic migration of glioma cells, which is facilitated along white fibers, assuming diffusion tensors
        with different diffusion coefficients along each candidate direction of growth. Our study extends this concept by fully
        exploiting the proportions of white and gray matter extracted by normal brain atlases, rather than discretizing diffusion
        coefficients. Moreover, the proportions of white and gray matter, as well as the diffusion tensors, are extracted by the
        respective atlases; thus, no DTI processing is needed. Finally, we applied this novel glioma growth model on real data
        and the results indicate that prognostication rates can be improved.

        system dynamic model and estimation theories, a new multisensor fusion algorithm, cascade orientation and position-
        estimation algorithm, is proposed for the integrated tracking device. The experimental results show that the proposed
        algorithms achieve accurate orientation and position tracking with robustness.

EGC     NeuroGlasses: A Neural Sensing Healthcare System for 3-D Vision Technology
6236

        3-D vision technologies are extensively used in a wide variety of applications. Particularly glasses-based 3-D technology
        facilities are increasingly becoming affordable to our daily lives. Considering health issues raised by 3-D video
        technologies, to the best of our knowledge, most of the pilot studies are practiced in a highly-controlled laboratory
        environment only. In this paper, we present NeuroGlasses, a nonintrusive wearable physiological signal monitoring
        system to facilitate health analysis and diagnosis of 3-D video watchers. The NeuroGlasses system acquires health-
        related signals by physiological sensors and provides feedbacks of health-related features. Moreover, the NeuroGlasses
        system employs signal-specific reconstruction and feature extraction to compensate the distortion of signals caused by
        variation of the placement of the sensors. We also propose a server-based NeuroGlasses infrastructure where
        physiological features can be extracted for real-time response or collected on the server side for long term analysis and
        diagnosis. Through an on-campus pilot study, the experimental results show that NeuroGlasses system can effectively
        provide physiological information for healthcare purpose. Furthermore, it approves that 3-D vision technology has a
        significant impact on the physiological signals, such as EEG, which potentially leads to neural diseases.



 EGC     Noise-Assisted Correlation Algorithm for Suppressing Noise-Induced Artifacts in
 6237
         Ultrasonic Nakagami Images

        Ultrasonic Nakagami images can complement conventional B-mode images for scatterer characterization. White noise in
        anechoic areas leads to artifacts that affect the Nakagami image to characterize tissues. Artifact removal requires
        rejection of the white noise without deforming the backscattered waveform. This study proposes a noise-assisted
        correlation algorithm (NCA) and carries out simulations, phantom experiments, and clinical measurements to validate its
        feasibility and practicality. The simulation results show that the NCA can reject white noise in an anechoic area without
        any deformation of the backscattered waveforms. The results obtained from phantoms and tissues further demonstrate
        that the proposed NCA can suppress a Nakagami image artifact without changing the texture of the Nakagami image of
        the scattering background. The NCA is an essential algorithm to construct artifact-free Nakagami image for correctly
        reflecting scatterer properties of biological tissues

         using a simulation tool based on the parallel finite-difference time-domain technique. This technique is well suited to
         model the radio propagation around complex, inhomogeneous objects such as the human body. The impact of different

         system performance are subject-specific and are associated with human genders, height, and body mass index.
         Maximum variations of almost 18.51% are observed in path loss exponent due to change of subject, which gives
         variations of above 50% in system bit error rate performance. Therefore, careful consideration of subject-specific
         parameters are necessary for achieving energy efficient and reliable radio links and system performance for body-
         centric wireless network.

 EGC     Personalization and Adaptation to the Medium and Context in a Fall Detection System
 6239

        The main objective of this paper is to present a distributed processing architecture that explicitly integrates capabilities
        for its continuous adaptation to the medium, the context, and the user. This architecture is applied to a falling detection
        system through: (1) an optimization module that finds the optimal operation parameters for the detection algorithms of
        the system devices; (2) a distributed processing architecture that provides capabilities for remote firmware update of the
        smart sensors. The smart sensor also provides an estimation of activities of daily living (ADL), which results very useful
        in monitoring of the elderly and patients with chronic diseases. The developed experiments have demonstrated the
        feasibility of the system and specifically, the accuracy of the proposed algorithms and procedures (100% success for
        impact detection, 100% sensitivity and 95.68% specificity rates for fall detection, and 100% success for ADL level
        classification). Although the experiments have been developed with a cohort of young volunteers, the personalization
        and adaption mechanisms of the proposed architecture related to the concepts of "design for all" and "design space"
        will significantly ease the adaptation of the system for its application to the elderly.
EGC      Prediction of Interstitial Glucose Level
6240

        Glucose is an important source of energy for cells. In clinical practice, we measure glucose level in blood and interstitial
        fluid. Each method has its pros and cons, and both levels correlate with each other. As the body tries to maintain the
        glucose level within a particular range to avoid adverse effects, it is desirable to predict future glucose levels in order to
        aid provided health care. We can see this desire in research, e.g., research on glucose transporters of cells. As yet
        another example, we can see it with diabetic patients, patients in a metabolic intensive care unit, particularly. In this
        paper, a glucose level prediction method is proposed.

        the local field potentials recorded in the motor area of the nucleus of Parkinson's disease patients undergoing deep
        brain stimulation. We use a segment of appropriately selected and processed data recorded from five nuclei to acquire
        the information of the spike timing and rhythm of a single neuron and estimate the model parameters. We then use the
        rest of each recording to assess the model's accuracy in predicting spike timing, rhythm, and interspike intervals. We

        of the CDF of the recorded spikes. By training the model appropriately, we prove its ability to provide quite accurate
        predictions for multiple-neuron recordings as well, and we establish its validity as a simple yet biologically plausible

EGC     Probabilistic Learning From Incomplete Data for Recognition of Activities of Daily Living
6242
        in Smart Homes

        Learning behavioral patterns for activities of daily living in a smart home environment can be challenged by the limited
        number of training data that may be available. This may be due to the infrequent repetition of routine activities (e.g.,
        once daily), the expense of using observers to label activities, and the intrusion that would be caused by the presence of
        observers over long time periods. It is important, therefore, to make as much use of any labeled data that are collected,
        however, incomplete these data may be. In this paper, we propose an algorithm for learning behavioral patterns for
        multi-inhabitants living in a single smart home environment, by making full use of all limited labeled activities, including
        incomplete data resulting from unreliable low-level sensors in this environment. Through maximum-likelihood
        estimation, using Expectation-Maximization, we build a model that captures both environmental uncertainties from
        sensor readings and user uncertainties, including variations in how individuals carry out activities. Our algorithm
        outperforms models that cannot handle data incompleteness, with increasing performance gains as incompleteness
        increases. The approach also enables the impact of particular sensors to be assessed and can thus inform sensor
        maintenance and deployment.



 EGC        Prognosis of Right Ventricular Failure in Patients With Left Ventricular Assist Device
 6243       Based on Decision Tree With SMOTE

        Right ventricular failure is a significant complication following implantation of a left ventricular assist device (LVAD),
        which increases morbidity and mortality. Consequently, researchers have sought predictors that may identify patients at
        risk. However, they have lacked sensitivity and/or specificity. This study investigated the use of a decision tree
        technology to explore the preoperative data space for combinatorial relationships that may be more accurate and
        precise. We retrospectively analyzed the records of 183 patients with initial LVAD implantation at the Artificial Heart
        Program, University of Pittsburgh Medical Center, between May 1996 and October 2009. Among those patients, 27 later
        required a right ventricular assist device (RVAD+) and 156 remained on LVAD (RVAD-) until the time of transplantation or
        death. A synthetic minority oversampling technique (SMOTE) was applied to the RVAD+ group to compensate for the
        disparity of sample size. Twenty-one resampling levels were evaluated, with decision tree model built for each. Among
        these models, the top six predictors of the need for an RVAD were transpulmonary gradient (TPG), age, international
        normalized ratio (INR), heart rate (HR), aspartate aminotransferase (AST), prothrombin time, and right ventricular
        systolic pressure. TPG was identified to be the most predictive variable in 15 out of 21 models, and constituted the first
        splitting node with 7 mmHg as the breakpoint. Oversampling was shown to improve the senstivity of the models

       synthetic RVAD+ oversampling was found to provide the best compromise between sensitivity and specificity, included
       TPG (layer 1), age (layer 2), right atrial pressure (layer 3), HR (layer 4,7), INR (layer 4, 9), alanine aminotransferase (layer
       5), white blood cell count (layer 5,6, &7), the number of inotrope agents (layer 6), creatinine (layer 8), A- T (layer 9, 10),
       and cardiac output (layer 9). It exhibited 85% sensitivity, 83% specificity, and 0.87 area under the receiver operating

EGC     Real-Time Sleep Apnea Detection by Classifier Combination
6244


       To find an efficient and valid alternative of polysomnography (PSG), this paper investigates real-time sleep apnea and
       hypopnea syndrome (SAHS) detection based on electrocardiograph (ECG) and saturation of peripheral oxygen (SpO2)
       signals, individually and in combination. We include ten machine-learning algorithms in our classification experiment. It
       is shown that our proposed SpO2 features outperform the ECG features in terms of diagnostic ability. More importantly,
       we propose classifier combination to further enhance the classification performance by harnessing the complementary
       information provided by individual classifiers. With our selected SpO2 and ECG features, the classifier combination
       using AdaBoost with Decision Stump, Bagging with REPTree, and either kNN or Decision Table achieves sensitivity,
       specificity, and accuracy all around 82% for a minute-based real-time SAHS detection over 25 sleep-disordered-

EGC    Rhythmogram-Based Analysis for Continuous Electrographic Data of the Human Brain
6245


       Ecologically relevant stimuli are rarely used in scientific studies because they are difficult to control. Instead,
       researchers employ simple stimuli with sharp boundaries (in space and time). Here, we explore how the rhythmogram
       can be used to provide much needed rigorous control of natural continuous stimuli like music and speech. The analysis
       correlates important features in the time course of stimuli with corresponding features in brain activations elicited by the
       same stimuli. Correlating the identified regularities of the stimulus time course with the features extracted from the
       activations of each voxel of a tomographic analysis of brain activity provides a powerful view of how different brain
       regions are influenced by the stimulus at different times and over different (user-selected) timescales. The application of
       the analysis to tomographic solutions extracted from magnetoencephalographic data recorded while subjects listen to
       music reveals a surprising and aesthetically pleasing aspect of brain function: an area believed to be specialized for
       visual processing is recruited to analyze the music after the acoustic signal is transformed to a feature map. The
       methodology is ideal for exploring processing of complex stimuli, e.g., linguistic structure and meaning and how it fails,
       for example, in developmental dyslexia.

EGC    Robust Real-Time-Constrained Estimation of Respiratory Motion for Interventional MRI on
6246
       Mobile Organs


       Real-time magnetic resonance imaging is a promising tool for image-guided interventions. For applications such as
       thermotherapy on moving organs, a precise image-based compensation of motion is required in real time to allow
       quantitative analysis, retrocontrol of the interventional device, or determination of the therapy endpoint. Reduced field-
       of-view imaging represents a promising way to improve spatial and / or temporal resolution. However, it introduces new
       challenges for target motion estimation, since structures near the target may appear transiently due to the respiratory
       motion and the limited spatial coverage. In this paper, a new image-based motion estimation method is proposed
       combining a global motion estimation with a novel optical flow approach extending the initial Horn and Schunck (H&S)
       method by an additional regularization term. This term integrates the displacement of physiological landmarks into the
       variational formulation of the optical flow problem. This allowed for a better control of the optical flow in presence of
       transient structures. The method was compared to the same registration pipeline employing the H&S approach on a
       synthetic dataset and in vivo image sequences. Compared to the H&S approach, a significant improvement (p <; & 0.05)
       of the Dice's similarity criterion computed between the reference and the registered organ positions was achieved.



EGC    Secure Management of Biomedical Data With Cryptographic Hardware
6247


       The biomedical community is increasingly migrating toward research endeavors that are dependent on large quantities
       of genomic and clinical data. At the same time, various regulations require that such data be shared beyond the initial
       collecting organization (e.g., an academic medical center). It is of critical importance to ensure that when such data are
       shared, as well as managed, it is done so in a manner that upholds the privacy of the corresponding individuals and the
       overall security of the system. In general, organizations have attempted to achieve these goals through deidentification
       methods that remove explicitly, and potentially, identifying features (e.g., names, dates, and geocodes). However, a
       growing number of studies demonstrate that deidentified data can be reidentified to named individuals using simple
       automated methods. As an alternative, it was shown that biomedical data could be shared, managed, and analyzed
       through practical cryptographic protocols without revealing the contents of any particular record. Yet, such protocols
       required the inclusion of multiple third parties, which may not always be feasible in the context of trust or bandwidth
       constraints. Thus, in this paper, we introduce a framework that removes the need for multiple third parties by collocating
       services to store and to process sensitive biomedical data through the integration of cryptographic hardware. Within
       this framework, we define a secure protocol to process genomic data and perform a series of experiments to
       demonstrate that such an approach can be run in an efficient manner for typical biomedical investigations.

EGC     Semantic Image Retrieval in Magnetic Resonance Brain Volumes
6248


        Practitioners in the area of neurology often need to retrieve multimodal magnetic resonance (MR) images of the brain to
        study disease progression and to correlate observations across multiple subjects. In this paper, a novel technique for
        retrieving 2-D MR images (slices) in 3-D brain volumes is proposed. Given a 2-D MR query slice, the technique identifies
        the 3-D volume among multiple subjects in the database, associates the query slice with a specific region of the brain,
        and retrieves the matching slice within this region in the identified volumes. The proposed technique is capable of
        retrieving an image in multimodal and noisy scenarios. In this study, support vector machines (SVM) are used for
        identifying 3-D MR volume and for performing semantic classification of the human brain into various semantic regions.
        In order to achieve reliable image retrieval performance in the presence of misalignments, an image registration-based
        retrieval framework is developed. The proposed retrieval technique is tested on various modalities. The test results
        reveal superior robustness performance with respect to accuracy, speed, and multimodality

       transfer function. Its usefulness was most evident when the subject's pulse transit time deviated from normative values.
       In these circumstances, the ITF yielded statistically significant reductions over a nonindividualized transfer function in
       the following three parameters: 1) 30% reduction in the root-mean-squared error between estimated versus actual
       central aortic blood pressure waveform (p <; 10-4), 2) >;50% reduction in the error between estimated versus actual
       systolic and pulse pressures ( p <; 10), and 3) a reduction in the overall breakdown rate (i.e., the frequency of estimation
       errors >;3 mmHg, p <; 10-4). In conclusion, the ITF may offer an attractive alternative to existing methods that estimates
       the central aortic blood pressure waveform, and may be particularly useful in nonnormative physiologic conditions.

       Topic Mining over Asynchronous Text Sequences


       Time stamped texts, or text sequences, are ubiquitous in real-world applications. Multiple text sequences are often
       related to each other by sharing common topics. The correlation among these sequences provides more meaningful and
       comprehensive clues for topic mining than those from each individual sequence. However, it is nontrivial to explore the
       correlation with the existence of asynchronism among multiple sequences, i.e., documents from different sequences
       about the same topic may have different time stamps. In this paper, we formally address this problem and put forward a
       novel algorithm based on the generative topic model. Our algorithm consists of two alternate steps: the first step
       extracts common topics from multiple sequences based on the adjusted time stamps provided by the second step; the
       second step adjusts the time stamps of the documents according to the time distribution of the topics discovered by the
       first step. We perform these two steps alternately and after iterations a monotonic convergence of our objective function
       can be guaranteed. The effectiveness and advantage of our approach were justified through extensive empirical studies
       on two real data sets consisting of six research paper repositories and two news article feeds, respectively

EGC    Tumor Recognition in Wireless Capsule Endoscopy Images Using Textural Features and
6255
       SVM-Based Feature Selection

       Tumor in digestive tract is a common disease and wireless capsule endoscopy (WCE) is a relatively new technology to
       examine diseases for digestive tract especially for small intestine. This paper addresses the problem of automatic
       recognition of tumor for WCE images. Candidate color texture feature that integrates uniform local binary pattern and
       wavelet is proposed to characterize WCE images. The proposed features are invariant to illumination change and
       describe multiresolution characteristics of WCE images. Two feature selection approaches based on support vector
       machine, sequential forward floating selection and recursive feature elimination, are further employed to refine the
       proposed features for improving the detection accuracy. Extensive experiments validate that the proposed computer-
       aided diagnosis system achieves a promising tumor recognition accuracy of 92.4% in WCE images on our collected
       data.

       Traditional clustering techniques are inapplicable to problems where the relationships between data points evolve over
       time. Not only is it important for the clustering algorithm to adapt to the recent changes in the evolving data, but it also
       needs to take the historical relationship between the data points into consideration. In this paper, we propose ECKF, a
       general framework for evolutionary clustering large-scale data based on low-rank kernel matrix factorization. To the best
       of our knowledge, this is the first work that clusters large evolutionary data sets by the amalgamation of low-rank matrix
       approximation methods and matrix factorization-based clustering. Since the low-rank approximation provides a compact
       representation of the original matrix, and especially, the near-optimal low-rank approximation can preserve the sparsity
       of the original data, ECKF gains computational efficiency and hence is applicable to large evolutionary data sets.
       Moreover, matrix factorization-based methods have been shown to effectively cluster high-dimensional data in text
       mining and multimedia data analysis. From a theoretical standpoint, we mathematically prove the convergence and
       correctness of ECKF, and provide detailed analysis of its computational efficiency (both time and space). Through
       extensive experiments performed on synthetic and real data sets, we show that ECKF outperforms the existing methods
       in evolutionary clustering.

       Video Distribution Techniques Over WiMAX Networks for m-Health Applications



       In this paper, we propose a novel approach for video distribution over IEEE 802.16 networks for mobile Healthcare (m-

       taking advantage of a flexible quality of service functionality offered by IEEE 802.16/WiMAX technology. The proposed
       technique is thoroughly investigated using network simulator software under various real-life m-Health scenarios, which
       include streaming video over medium access control layer service connections. It is shown that the technique is fully
       compatible with the WiMAX standard specification and allows a 9-16% increase in the overall network throughput, which
       is dependent upon the initial system configuration and the selection of WiMAX user parameters

       Wavelet-Based Energy Features for Glaucomatous Image Classification



       Texture features within images are actively pursued for accurate and efficient glaucoma classification. Energy
       distribution over wavelet subbands is applied to find these important texture features. In this paper, we investigate the
       discriminatory potential of wavelet features obtained from the daubechies (db3), symlets (sym3), and biorthogonal
       (bio3.3, bio3.5, and bio3.7) wavelet filters. We propose a novel technique to extract energy signatures obtained using 2-D
       discrete wavelet transform, and subject these signatures to different feature ranking and feature selection strategies. We
       have gauged the effectiveness of the resultant ranked and selected subsets of features using a support vector machine,
       sequential minimal optimization, random forest, and naive Bayes classification strategies. We observed an accuracy of
       around 93% using tenfold cross validations to demonstrate the effectiveness of these methods.



EGC    Wireless Capsule Endoscopy Video Segmentation Using an Unsupervised Learning
6259   Approach Based on Probabilistic Latent Semantic Analysis With Scale Invariant Features

       Since wireless capsule endoscopy (WCE) is a novel technology for recording the videos of the digestive tract of a
       patient, the problem of segmenting the WCE video of the digestive tract into subvideos corresponding to the entrance,
       stomach, small intestine, and large intestine regions is not well addressed in the literature. A selected few papers
       addressing this problem follow supervised leaning approaches that presume availability of a large database of correctly
       labeled training samples. Considering the difficulties in procuring sizable WCE training data sets needed for achieving
       high classification accuracy, we introduce in this paper an unsupervised learning approach that employs Scale Invariant
       Feature Transform (SIFT) for extraction of local image features and the probabilistic latent semantic analysis (pLSA)
       model used in the linguistic content analysis for data clustering. Results of experimentation indicate that this method
       compares well in classification accuracy with the state-of-the-art supervised classification approaches to WCE video
       segmentation.
