ABSTRACT:
An X-ray apparatus capable of X-ray beaming in a multiplicity of directions around and through the body of a patient lying horizontally stationary on a table. The X-ray equipment is fixed to a ring which circumscribes the table and the patient. This ring is held on a support and is able to be driven into rotation, relative to the support, about its center. The apparatus also includes a fork-like suspension member which has a pair of side legs located each on one outward side of the support; the lower ends of the legs being connected with the support such as to allow the latter, and the ring it holds, to be oscillated in unison by a suitable motor mechanism about a horizontal axis joining the two lower ends of the legs; this horizontal axis being further normal to the axis of rotation of the ring. The suspension member is in turn connected to a carrier assembly provided on a top structure of the frame of the X-ray apparatus. This assembly includes a carrier on which the suspension member is centrally mounted for displacement over the patient's table as well as for rotation of the suspension member, and hence the ring and the X-ray equipment fixed on it, about a vertical axis which intersects the axes of ring rotation and oscillation.
