Abstract

In medical X-ray apparatus including a stand mounting an X-ray tube and two X-ray receptors such as an image intensifier and a film exchanger, the two X-ray receptors are mounted on a common frame pivoted to present either receptor at the image plane of the X-ray tube. Additionally the two receptors slide on the frame and are linked by a bell crank for coordinated rotation and sliding movement which restores their common center of gravity to its initial locus as one receptor is interchanged for the other. Balance of the receptors with the X-ray tube on the frame is thereby maintained.
