Abstract
An x-ray tube has a stationary cathode and a rotating anode contained in an evacuated housing. The anode is mounted on a stationary shaft on bearings. The anode has a hollow interior, in which a stationary heat-absorption member is disposed, also mounted to the shaft. The shaft is in the form of a tube, with the interior thereof being charged by a coolant. The coolant circulates through the heat-absorption member within the hollow interior of the anode to dissipate heat from the anode generated during the production of x-rays.
