ABSTRACT:
An x-ray examination apparatus in which an opposed x-ray source and x-ray image detector, which establish a radiation vector and an image orientation direction traverse to said vector, are mounted to be positioned relative to a series of three independently operable axes of rotation. Computing and measuring means are provided by which angular positions of rotation about the various axes can be correlated to simultaneously achieve both a desired angular orientation of the radiation vector and a desired direction of image orientation.
