Computed tomography scan synonyms, Computed tomography scan pronunciation, Computed tomography scan translation, English dictionary definition of Computed tomography scan. Computed tomography scanning, also called CT scan, CAT scan, or computerized axial tomography, is a diagnostic tool that provides views of internal body structures using x rays. A computerized tomography (CT) scan combines a series of X-ray images taken from different angles around your body and uses computer processing to create cross-sectional images (slices) of the bones, blood vessels and soft tissues inside your body. CT scan definition is - a cross-sectional, three-dimensional image of an internal body part produced by computed tomography chiefly for diagnostic purposes —called also CAT scan. During the process a series of x-ray photographs are taken from different angles and then combined by computer into a composite 3-dimensional representation. In comparison to the traditional X-ray image, where you can see only coarse structures and bones, a CT scan also captures soft tissues with little contrast difference in detail. Virtually all tomography today is computed tomography.
