What is a CAT Scanner?
CAT stands for computerized axial tomography, a way of taking photographs of cross sections of diseased tissue 100 times more detailed than by the traditional X-ray method.
The inventor was Godfrey Hounsfield of Britain’s Electrical and Musical Industries, the company that first brought television into the home. The first CAT scanner in clinical use entered medical history in 1972 when it was used to diagnose a brain tumor in a woman patient in Wimbledon, England.
Hounsfield shared the Nobel Prize for physiology and medicine with American inventor Allan Cormack, who had independently worked on the principles of CAT scanning.
