[1970-75]
* * *
diagnostic imaging method using a low-
dose beam of X-rays that crosses the body in a single plane at many different angles.
Computerized axial tomography was conceived by William Oldendorf and developed independently by Godfrey Newbold Hounsfield (
Hounsfield, Sir Godfrey Newbold)
and Allan MacLeod Cormack (
Cormack, Allan MacLeod),
who shared a 1979 Nobel Prize for their inventions.
A major advance in imaging technology,
it became generally available in the early 1970s.
Detectors record the strength of the exiting X-
rays;
this information is then processed by computer to produce a detailed two-
dimensional cross-
sectional image of the body.
A series of such images in parallel planes or around an axis can show the location of abnormalities (
especially tumours and other masses)
more precisely than can conventional X-
ray images.
