Computed Tomography

Definition of Computed Tomography:

A scanning procedure using X-rays and a computer to detect abnormalities of the body's organs.  This technique provides cross-sectional images of body organs, which is much clearer than those provided by conventional X-rays.

Also: CAT Scan, Computerised Tomography, Computerized Axial Tomography, Computerized Tomography, CT Scan
