摘要： In an X-ray tomographic apparatus, while rotating a gantry rotary section around a region where an object to be photographed is placed, the anode target of an X-ray tube is rotated at a predetermined high rotation rate and X-rays are emitted from the anode target. In emitting the X-rays, the rotation torque is increased to be larger than that prior to rotation of the gantry rotary section in accordance with the rotation drive power supplied to a stator coil. A decrease in rotation rate of the anode target of the X-ray tube can be prevented even during rotation of the gantry rotary section, radiation at a necessary and sufficient X-ray dose can be assured, and an X-ray tomographic image can be properly obtained.

摘要： A rotary anode X-ray tube, comprising a rotor, a stationary structure, a dynamic pressure slide bearing formed between the rotor and the stationary structure, the stationary structure having a lubricant storage chamber and provided with a lubricant passageway, and a vacuum vessel. Holes are formed in the stationary structure extending from the lower edge surface along the tube axis and not to cross the lubricant storage chamber and the lubricant passageway. Heat transfer members for the stationary structure having a heat conductivity higher than that of the stationary structure are inserted into the holes, respectively. A heat transfer member having a heat conductivity higher than that of the inner cylindrical structure of the rotor is bonded in a cylindrical form to the outer circumferential wall of the inner cylindrical structure constituting a bearing. A heat transfer member can be mounted to each of the rotor and the stationary structure.
