ABSTRACT
A machine for examining the interior of a patient which includes a movable support for the patient, a frame having an opening adapted to circumscribe the patient, a shutter assembly, an X-ray beam source mounted on one side of the opening with a detector unit mounted on the opposite side of the opening such that a beam emitted by the source passes through the patient prior to reception by the detector. The machine includes mechanisms for rotating the framework about the patient while there is a relative translational movement of the X-ray source and receptor relative thereto. The apparatus also includes mechanism for tilting the framework such that other-than-vertical planes may be examined. The opening of the machine is sufficiently large to receive a human body and eliminates the requirement of water bags and other such paraphernalia commonly associated with equipment of this type.
