CT Scan

Provided by A.D.A.M.

Alternate Names : CAT Scan, Computed Axial Tomography (CAT) Scan


Definition

Computed tomography (CT) a method of body imaging in which a thin x-ray beam rotates around the patient. Small detectors measure the amount of x-rays that make it through the patient or particular area of interest.

A computer analyzes the data to construct a cross-sectional image. These images can be stored, viewed on a monitor, or printed on film. In addition, three-dimensional models of organs can be created by stacking the individual images, or "slices."
