What is a CT Scan?

A computerized axial tomography scan (CAT), or computerized tomography scan (CT), uses a series of x-rays taken at different angles to produce a detailed image of a particular section of the body.

How it Works

An x-ray machine sends one radiation beam to a still body. A CT scanner, on the other hand, sends out multiple radiation beams to a moving body, as it slides through the machine.

Once the scan is complete, the x-ray data is processed by a computer and combined to create either a 2-dimensional or 3-dimensional image.
