ABSTRACT:
Apparatus for examining a human patient by means of penetrating radiation has a source of radiation for producing a sectoral swath of radiation which traverses a planar slice of the patient and is then measured by a bank of detectors each of which is sensitive to a narrow beam of the radiation in said swath. The swath of radiation is produced by a rotating anode Collidge tube and means are provided for monitoring the radiation intensity at spaced positions across the width of the swath and for taking account of variations of the intensity in the output signals derived from the detectors. Preferably radiation emitted from the anode at near tangential directions is selected to form the swath.
