computed tomography

Computed tomography (CT), originally known as computed axial tomography (CAT or CT scan) and body section roentgenography, is a medical imaging method employing tomography where digital geometry processing is used to generate a three-dimensional image of the internals of an object from a large series of two-dimensional X-ray images taken around a single axis of rotation. The word "tomography" is derived from the Greek tomos (slice) and graphein (to write). CT produces a volume of data which can be manipulated, through a process known as windowing, in order to demonstrate various structures based on their ability to block the X-ray beam. Although historically (see below) the images generated were in the axial or transverse plane ( to the long axis of the body), modern scanners allow this volume of data to be reformatted in various planes or even as volumetric (3D) representations of structures.

Noun
1. a method of examining body organs by scanning them with X rays and using a computer to construct a series of cross-sectional scans along a single axis
(synonym) computerized tomography, CT, computerized axial tomography, computed axial tomography, CAT
(hypernym) X-raying, X-radiation

An x-ray procedure that uses a computer to produce a detailed picture of a cross section of the body; also called CAT or CT scan.

[tuh-MAH-gra-fee]
CT scan. A series of detailed pictures of areas inside the body taken from different angles; the pictures are created by a computer linked to an x-ray machine. Also called computerized tomography and computerized axial tomography (CAT) scan.
