A method for restructuring images ofsoft tissues from measurements of discontinuities of ra-diodensity was described by William Henry Oldendorf

in 1961 [1]. Improvements led, 14 years later, to SirGodfrey Hounsfield’s description of computer assistedtomography [2], for which Hounsfield received the1979 Nobel Prize for Medicine.
