ABSTRACT:
The invention relates to apparatus for examining a body by means of penetrating radiation in which a source of radiation produces a beam of radiation which passes through the body, and a detector receives the radiation emerging from the body. The source and the detector are mounted on a scanning structure which can undergo successive lateral scans at a succession of orbital positions so that a plane section of the body is traversed by a set of parallel beams at each of the orbital positions. A reference attenuator provides a known attenuation of the beam at the beginning of each lateral scan, and means are provided for modifying the output signals during each lateral scan in response to the signal obtained when the beam is passing through the reference attenuator. In this way compensation is effected for rapid changes in the sensitivity of the detector.
