Also known as X-ray computed tomography, CT scan, CAT scan, CT, CAT, CT machine, CT Machine, tomography
medical imaging procedure using X-rays to produce cross-sectional images
AI overview
Computed tomography, or CT, is a medical imaging technique that uses X-rays to create detailed cross-sectional pictures of the inside of your body. Doctors use CT scans to diagnose diseases, plan treatments, and monitor health conditions by examining these internal images.

Article
A computed tomography scan (CT scan), formerly known in a more rudimentary state as computed axial tomography scan (CAT scan), is a medical imaging technique used to obtain detailed internal images of the body. 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 a 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 tomographic reconstruction algorithms to produce tomographic (cross-sectional) images (virtual "slices") of a body. CT scans can be used in patients with metallic implants or pacemakers, for whom magnetic resonance imaging (MRI) is contraindicated. 1977 Dutch newsreel about CT scan
