Abstract
An X-ray source and a detector array are mounted on opposite sides of a generally horizontally extending longitudinal axis of a rotating base. The rotating base is journaled on a tiltable frame. The frame is supported on curved tracks for tilting by translating along a curved path about a fixed transverse virtual axis of rotation which is perpendicular to and intersects the rotational axis of the rotating base. Tilting the frame permits making an X-ray scan through a layer of a patient which is at an acute angle relative to the longitudinal axis. The azimuth drive for the rotatable frame utilizes a toothed belt. A self-acting friction brake is provided for constraining the rocking base. A hoist is provided for making installation and removal of the X-ray source convenient.
