摘要： An X-ray apparatus comprising an anode target (11) for generating X-rays, an electron radiation source (17) for generating an electron to the anode target (11), a rotor (15) which is connected to the anode target, a stator (19) for generating a driving force to rotate the rotor (15), a shaft (13a) which rotatably supports the rotor (15) through a bearing, and an enclosure (9) which keeps at least the anode target (11), the electron radiation source (17) and the rotor (15) at a predetermined vacuum. A housing (3) is provided which contains the enclosure (9) and a cooling medium (7) around the enclosure (9). A cooling medium flow path is provided for circulating the cooling medium (7) along a route inside the shaft (13a), in the vicinity of a recoil electron capture trap (23), and in the vicinity of the anode target (11) in that order. Further, a pump (21a) for circulating the cooling medium (7) trough the cooling medium flow path, and a heat exchanger (21b) for radiating the heat transmitted by the cooling medium (7) circulated by the pump (21a) are provided.

摘要： In an X-ray tube (31) with a hydrodynamic slide bearing, an electron beam is caused to strike the focal point track area F on its rotary anode, which then emits X rays. An X-ray emission control device (29) that sets the conditions for emitting the X rays stores as data the rises and drops in the temperature at the electron beam incident point and the other part on the focal point track surface of the anode. On the basis of the data, the input permission or inhibition conditions for the X-ray tube at every moment are calculated and the resulting conditions are displayed on a display unit (61). As a result, it is possible to perform a computing process in advance to determine whether or not X rays can be emitted under specific conditions without permitting the rotary anode in the X-ray tube with a hydrodynamic slide bearing to melt and then display the results, thereby enabling a safe, efficient photographing control.

摘要： In an X-ray tomographic apparatus, while rotating a gantry rotary section (15) around a region where an object to be photographed is placed, the anode target (26) 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 (28b). 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.
