A technique for imaging anatomical structures using x-ray. Objects are exposed to a series of x-ray beams on a single plane but with origin at different points around a 180-degree arc. A computer algorithm recon- structs the beam absorption data so as to display an image of absorption values at each point in the plane. The process is repeated for each plane to be imaged. Used for anatomical abnormalities such as strokes, tumor, atrophy of the brain.
CT scanning, an acronym for computerized axial tomographic scanning, is a widely recognized term used to refer to this imaging technique.
