A computerized tomography or CT takes data from multiple x-ray images and uses a computer to create an image. Tomography is defined as the process of creating a two-dimensional image from a section of a three-dimensional object.
The CT was invented by Godfrey Hounsfield, a British engineer, and Allan Cormack, a physicist from South Africa. Their combined efforts resulted in the production of the first CT scanner and the computer program needed to take the raw data and create the images. Together, Hounsfield and Cormack received the Nobel Peace Prize for their work and contributions to science and medicine.
The first CT used in a clinical setting was installed between 1974 and 1976. It was originally used for only images of the head, however, it developed into systems that could be us
