ABSTRACT:
An X-ray CT scanner contains a cable-handling device provided with a ring-shaped housing for receiving a cable member. A plurality of rollers are interposed between a rotatable inner peripheral and a fixed outer peripheral member of the ring-shaped housing. The cable member is wound around the inner peripheral member at least once, then wound about half the periphery of a specified roller, and finally wound around the outside of the group of the rollers in a direction opposite to that in which the cable member is wound within the housing. The end portions of the cable member facing the inner and outer peripheral members of the housing are fixed thereto. Mounted on a rotating frame are an X-ray tube, X-ray detector and high voltage generator. The high voltage generator and X-ray tube are connected together by a short high voltage cable. The inner peripheral member is rotated with the rotating frame. The cable member is wound around the inner peripheral member or unwound therefrom. The rollers are provided between the cable member wound around the inner peripheral member and the cable member wound around the outside of the group of rollers. The rollers are driven with the rotation of the inner peripheral member of the housing, thereby preventing the cable member from being displaced from the regular rotation course.
