 In 1967 an electronics engineer from EMI, Godfrey Hounsfield, visited consultant radiologist Jamie Ambrose to discuss a new method of using X-rays to image the brain.Although Hounsfield had been dismissed as a crank by a neuroradiologist at the National Hospital for Neurology and Neurosurgery, Ambrose and other staff thought the proposal was interesting.Ambrose gave him a bottled brain tumour sample to see if he could make good on his claim that "I can do better" than their state-of-the-art X-ray and ultrasound images.
