Who invented the CAT Scanner?

The CAT scanner, or CT (computed tomography) scanner, was invented by British engineer Godfrey Hounsfield and German physicist Allan Cormack. Their pioneering work in the early 1970s led to the development of the first practical CT scanner, which was introduced in 1971. Hounsfield and Cormack were awarded the Nobel Prize in Physiology or Medicine in 1979 for their contributions to medical imaging.
