A CT scan is also known as computed tomography scan (formerly known as computed axial tomography or CAT scan).
It is a medical imaging technique used in radiology to get detailed images of the body noninvasively for diagnostic purposes.
The personnel that perform CT scans are called radiographers or radiology technologists.
CT scanners use a rotating x-ray tube and a row of detectors placed in the gantry to measure X-ray attenuations by different tissues inside the body.
The multiple X-ray measurements taken from different angles are then processed on a computer using reconstruction algorithms to produce tomographic (cross-sectional) images (virtual “slices”) of a body.
The use of ionizing radiations sometimes restricts its use owing to its adverse effects.
