ABSTRACT:
A contoured X-ray imaging system consists of an X-ray source and X-ray film holding cassette for taking X-ray pictures closely adjacent to a body surface without unnecessary exposure of adjacent body parts to X-rays. The X-ray cassette is contoured to the outline of a structure or a body part to evaluate it without the radiation spreading unnecessarily to the adjacent areas. The X-ray cassette is a thin flat box which has an edge wall contoured outline of the subject or an adjacent structure. The X-ray source and intervening shields or the like are each configured to project an X-ray beam which is contoured in the same contour as the film-holding cassette so that the X-rays reach the film in the same contour as avoid unnecessary exposure of adjacent portions of the body to the X-rays.
