(3) Computerised Axial Tomography or CAT is a radiologic imaging modality that uses computer processing to generate an image (CAT scan) of the tissue density in a "slice" as thin as 1 to 10 mm in thickness through the patient's body. As compared to the X-Ray the slice of the body under the CAT Scan is 100 times more clear.
