Telemedicine was initially performed with telephone and radio but is now used with video telephony, advanced diagnostic methods, and distributed client-server applications.
c. Diagnostic—Technological advances in radiology have given rise to advanced methods of X-ray and imaging services. Computers allow radiologists and technicians to study and print the final images.
X-rays and CT (computed tomography) scans use radiation to produce images of a patient's internal structure and to find abnormalities.
X-rays allow the patient's internal structure to be seen from one perspective. CT scans, on the other hand, use computer technology to convert multiple X-ray images, which are multiple two-dimensional X-ray images, into a multidimensional picture to help doctors make the diagnosis.
Magnetic resonance imaging, commonly known as MRI, is the process of mapping a patient's internal structure and movement using a powerful magnetic field.
MRI is used to produce detailed images of soft tissues in the body without using radiation. The bioelectrical activity of the body is detected by the MRI machine, and the interpretation of the structure of this area is scanned.
The movement of this area is given to a computer, which gives a three-dimensional presentation of it and gives the doctor an idea of its structure. It provides detailed information to help doctors discover anatomical and operational defects in patients without invasive surgery.
