The Evolution of CT Scan Clinical Trials. Submitted by Bioclinica on July 22, 2011 - 11:46am. On October 1, 1971, CT scanning was first introduced by Godfrey Hounsfield into medical practice with a successful scan on a patient at the Atkinson Morley Hospital in Wimbledon, London using a prototype scanner.
Who invented CAT-Scans? CAT scan was invented by two people Godfrey Hounsfield from EMI Laboratories in England and Allan Cormack from Tufts University in Massachusetts in 1972. In the second generation full body CT scans were introduced and 20 or more X-ray beams and detectors were used which improved the quality of the image greatly. 2  Many developments were made in the present day CT scan device and you can complete the entire scan of the body within one-third of a second.
