Computed Tomography

In 1935, Grossman coined the term “tomography” from the Greek “tomos”, meaning section or cut, to denote the method using conventional radiography to depict specific layers within the human body. In conventional tomography the image of the section is orientated parallel to the film. Computed tomography (CT) refers to the method of obtaining information from the passage of x-ray beams through a selected area of the body which in turn is processed with the aid of a sophisticated computer. The computer then produces clear sharp images of the internal structure of the body in the axial plane.
