in which decade was the ct scanner developed
CT scan The history of X-ray computed tomography goes back to at least 1917 with the mathematical theory of the Radon transform.[104][105] In October 1963, Oldendorf received a U.S. patent for a "radiant energy apparatus for investigating selected areas of interior objects obscured by dense material".[106] The first commercially viable CT scanner was invented by Sir Godfrey Hounsfield in 1967.[107]
