Abstract
Abstract An X-ray table top is moveably supported by a shaft extending from a support mechanism on a base to the end of the table top at one longitudinal side thereof offset from the longitudinal axis of the top. The support mechanism includes means for raising and lowering the table top, Trendelenburg tilting the top about an axis transverse of its longitudinal axis and canting it about the longitudinal axis or an axis parallel thereto. The offset support connection to the table top allows unobstructed access to both sides, the foot end, and to the head end of the table top for anesthesiological personnel and equipment.
