What is Imaging Informatics?
Imaging informatics- “a subspecialty of
Biomedical Informatics that aims to improve the
efficiency, accuracy, usability and reliability of
medical imaging services within the healthcare
enterprise. It is devoted to the study of how
information about and contained within medical
images is retrieved, analyzed, enhanced, and
exchanged throughout the medical enterprise.”
What is teleradiology?
Teleradiology is “the transmission of
radiological patient images, such as x-rays,
CTs, and MRIs, from one location to another
for the purposes of interpretation and/or
Why would a facility use teleradiology?
Facilities would use teleradiology:
If they are short on radiologists at the time
if they do not have any radiologists at all.
If they need to consult a sub-specialized
How does it work?
Teleradiology uses specialized programs that
transfer the use networks, such as the
Internet and LAN, to transfer images.
What is nighthawking?
Nighthawking is using teleradiology to transfer
images at night to radiologists who are
available. It’s basically another name for
There is always a radiologist available to read
scans or for second opinions.
It could help hospitals obtain and keep
radiologists because many radiologists do not
prefer to do the night shift.
Reimbursement for radiologists from
insurance companies may drop because
teleradiology companies charge less.
Teleradiologists lack the patient’s records,
which could affect the diagnosis.
What is the Sonic Flashlight?
The sonic flashlight is a
device that places “the
and a flat-panel display
on opposite sides of a
When the doctor looks
through the mirror an
ultrasound is visible and
perfectly aligned with
the patient’s skin.
It’s like having x-ray vision
Why would this be used?
To give the doctor a better sense of the
It would also make it easier for the doctor to
do invasive procedures without having to
look back and forth between the patient and
the ultrasound display screen.
What is PACS?
“combination of hardware and software dedicated to
the short and long term storage, retrieval,
management, distribution and
presentation of images.”
The first large-scale
PACS installation was at
the University of
Kansas, Kansas City
What Are PACSs Used For?
Electronic image integration platform
Radiology workflow management
A secure network
Modality Reading workstation
QA workstation Reporting package
Back-Up and Archive
PACS image backup is critical
PACS should have one place to access for data
All PACS should interface with existing hospital
A more reliable dataset can be created through
interfacing between multiple systems
An interface can improve workflow patterns
Fully integrated RIS/PACS are being developed

– Breast Cancer
– Lung Cancer
– Colon Cancer
– Prostate Cancer
– Bone Metastases
– Coronary Artery Disease
– Congenital Heart Defect
