ABSTRACT:
An overhead X-ray apparatus for imaging in the bi-plane configuration which apparatus has the radiation isocenter vertically displaceable. A C-arm (or a like) for supporting an X-ray tube and image receptor is mounted on a carriage assembly in a rotatable arrangement about a vertical axes. The carriage assembly comprises a support frame and a slideable support mounted on overhead rails coupled by a scissor mechanism. A distance between the support frame and the slideable support and, hence the vertical position of the radiation isocenter can be varied by action of chains or timing belts connecting the support frame with the anchoring member which moves along the slideable support while actuated by an actuator.
