The first CT Scan was performed at Atkinson Morley Hospital in Wimbledon, London, in 1975.

Godfrey Hounsfield was born in Sutton-on-Trent, Nottinghamshire, England. He perfected the Computed Axial Tomography scanner, CAT scan for short.

He worked for EMI and became interested in computers. In 1958, he helped design the first commercially available all-transistor computer made in Great Britain, the EMIDEC 1100.

With the success of the Beatles EMI had money to invest and asked Hounsfield, who had now transferred to EMI Central Research Laboratories, to come up with a new area of research. 1 He came up with the idea that one could determine what was inside a box by taking X-ray readings at all angles around the object. Godfrey thought he could use a computer to take images from X-rays at various angles and create a 3d image of the object.

Prototype

Hounsfield started with a prototype head scanner. He experimented on a preserved brain and the results were encouraging. He then used it on a cow brain from a butcher shop, eventually Godfrey scanned his own brain. The medical world, and EMI, were now excited at the potential of this new technology.
