ABSTRACT:
An arc-shaped X-ray beam penetrates an arcual cross-sectional area of a body and the attentuated transmitted beam irradiates a portion of a circular array of detectors on a rotating disc. The detectors operate to generate signals proportional to the intensity of the incident transmitted radiation. The beam and detectors are moved along the axis of the body during rotation of the disc to irradiate adjacent cross-sectional areas of the body. A computer operated CRT receives the detector signals and displays an image of the radiation attentuation characteristics of the scanned arcual areas.
