Computed Medical Imaging Nobel Lecture, 1979-12
By Godfrey N. Hounsfield, The Medical Systems Department of Central Research Laboratories EMI, London, England


In preparing this paper I realised that I would be speaking to a general audience and have therefore included a description of computed tomography (CT) and some of my early experiments that led up to the development of the new technique. I have concluded with an overall picture of the CT scene and of projected developments in both CT and other types of systems, such as Nuclear Magnetic Resonance (NMR). Although it is barely 8 years since the first brain scanner was constructed, computed tomography is now relatively widely used and has been extensively demonstrated. At the present time this new system is operating in some 1000 hospitals throughout the world. The technique has succesfully overcome many of the limitations which are inherent in conventional Xray technology.
