ABSTRACT:
An apparatus for exposing selected portions of a patient's body to X-radiation and imaging rays transmitted through the body onto a receiver, such as film, wherein an X-ray source and receiver are mounted on arms offset from opposite ends of a semicircular carrier member supported on a circumference thereof for rotation through at least a full 180.degree. arc in a vertical or tilted plane passing through the body. The centers of the carrier member and support mount are unobstructed and the extension arms are carried on a radially-inside surface of the carrier member to avoid interference between the parts during rotation through the arc. Three sets of bearings which are spaced-apart along a guide track in the support mount support the carrier member radially and axially with at least two of the bearings engaged with the carrier member even at extremes of rotation thereof.
