Medical Radiation Techniques: A Brief Insight
Medical imaging technology is an ever expanding field. It came into picture with X-rays,
followed by Ultrasonography, which took many years to evolve as a sophisticated
modality. Since then, three-dimensional imaging of deep seated anatomical structures
was made probable with the conception CT and MRI scans. The most recent and highly
advanced breakthrough in medical imaging technology, such as FMRI, PET, and SPECT
scanning, generate images of body function rather than anatomy.
A brief description of various technologies is given below:
Digital X-rays: Digital X-rays fabricate clear images with a comprehensive
assessment. Even the re-exposures are not considered essential. The X-Ray
finds a way through the patient's body and the digital camera captures the
consequential image. The images are stored for retrieval and final processing.
Through our digital X-Ray system, even the very fine details of the body can be
enhanced and the minutest of lesions can be examined.
Ultrasound: Ultrasound imaging uses frequencies from 2 to 18
MHz Ultrasonography has many significant diagnostic applications, the best-
known of which are obstetric ultrasounds and echocardiograms. Further, Doppler
sonography and a couple of non invasive procedures are also undertaken using
this technology. Sonographic assessments for In Vitro Fertilization procedures,
surgical and gynecological practices & portable bedside Ultrasonography are
also very popular.
Magnetic Resonance Imaging (MRI): MRI is a relatively novel skill to hit the
medical world, and has totally transformed the medical imaging and the
diagnostic processes. In-vivo images can be taken of the human body, signifying
that internal images can be seen without making any incisions. Entirely non-
intrusive procedures are used which makes MRI's very effective.
Positron Emission Tomography (PET): Like MRI, PET images characterize
biological processes occurring inside the body. Here, a tracer is injected into the
body. The tracer is a molecule used in metabolism which has an embedded
radioactive isotope with a short half-life that decays by emitting
positrons. Clinically, PET imaging is used in oncology and for detecting certain
brain disorders. PET scans are usually used in conjunction with CT or MRI
scans in a single medical imaging unit that can show both anatomy and biological
Miscellaneous: Medical imaging technology is a field of rapidly emerging
developments. Newer modalities comprise of optical imaging, making use of
low-frequency light (infrared and even radio waves), and photo acoustic imaging,
which takes advantage of the fact that under certain circumstances, matter can
emit a sound upon the absorption of light. This field promises remarkable new
possibilities for both anatomical and functional imaging.
A lot of universities all across the globe offer hands on training in the above stated
modalities, but one such academy, Wellwishers Academy offers unparallel training. The
academy (from the house of Marvel Group), prepares a trainee with an integrated clinical
experience from the beginning of the program. The trainees work within an inter-
professional health care team to become competent enough in providing safe patient
assessment, and acquire the diagnostic and therapeutic dexterity consistent with best
practice standards for medical radiation technology.
Wellwishers academy training healthcare professionals in the latest developments in
Medicine by its Paramedical courses and, Ultrasound Programs and CT/MRI Training.
Paramedical courses include more Programmes like: D.M.P.H.W (Diploma in Multi
Purpose Health Worker), 3d/4d Ultrasound Course
