the invention of computed tomograph

the invention of computed tomography has been credited to godfrey n. Hounsfield for his work in 1970-71, although preliminary work was done by oldendorf in 1961 and Cormack in 1963, and all three based their work on the investigations of the Austrian mathematican j. radon, who proved in 1917 that an image of a three-dimensional object could be produced from its mathematical projections. Hounsfield was a research engineer with electro-musical instruments Ltd. (EMI), the English firm that gained international renown as the beatles music publishers during the 1960s. his original scanner was built on a lathebed and required nine days to proceduce a single section image. Although the company sold its CT business, it continues to operate American and britsh EMI record labels. Hounsfield and Cormack were awarded the 1979, nobel prize for medicine. Hounsfield’s invention parallels rontgen discovery of x-rays as the two most outstanding contributions to medical imaging.
early CT units were capable of only axial tomopgraphy, and the term computerized axial tomography (CAT) scanning became a popular acronym. Modern CT units are capable of diverse modes much more complex than simple axial scanning. However, the term CAT scaning may encure, as have other antiquated radiologic terms (e.g flat plate and wet reading). A modern CT units incudes a gantry, table, x-ray tube, detectors, computer, display. Console and image storage units
