American physicist who shared the 1979 Nobel Prize for Medicine with Sir Godfrey Newbold Hounsfield for the development of the Computerized Axial Tomography (CAT) scanning system, which revolutionized noninvasive medical imaging and diagnosis. Cormack calculated the mathematical equations required for generating the three-dimensional CAT scan images of body organs. He was a professor of physics at Tufts University in Massachusetts, and served as the department's chairman from 1968 to 1976.
