While CT is most prominently used in medical diagnosis, it can also be used to form images of non-living objects. Since its development in the 1970s, CT scanning has proven to be a versatile imaging technique. CT scan can be used in patients with metallic implants or pacemakers, for whom magnetic resonance imaging (MRI) is contraindicated. The multiple X-ray measurements taken from different angles are then processed on a computer using tomographic reconstruction algorithms to produce tomographic (cross-sectional) images (virtual "slices") of a body. ĬT scanners use a rotating X-ray tube and a row of detectors placed in a gantry to measure X-ray attenuations by different tissues inside the body. The personnel that perform CT scans are called radiographers or radiology technologists. A computed tomography scan ( CT scan formerly called computed axial tomography scan or CAT scan) is a medical imaging technique used to obtain detailed internal images of the body. ![]()
