CAT stands for computer axial tomography.  It is a highly specialized, computer assisted type of x-ray scanner.  The person is placed inside a scanning machine and the x-ray scanner rotates 360 degrees around the person or the specific area being scanned.  The results of the scans are then processed by a computer system to produce a 3D image of the scanned area.  Importantly, cross-sectional "slices" in a particular area of the body can be viewed for a thorough view in the body.  Traditional x-rays merely produce a flat image with no depth.  Another advantage of a CAT scanner is that it has a much higher visual resolution and can differentiate between different types of tissues in the body based on their abilities to block x-ray beams.
