Abstract
An X-ray tube with a rotatable anode for generating X-rays and an X-ray apparatus and a method for balancing the rotary anode of an X-ray tube include balancing of the rotary anode applicable to an anode mounted inside an X-ray tube. The rotatable anode includes an anode disc fixedly mounted to a rotatably driven support body, which is rotatably supported by a bearing arrangement. The anode includes at least one balancing cavity to adjust the center of gravity of the anode. The balancing cavity is partly filled with a balancing material being solid at operating temperature of the X-ray tube and liquid at a higher temperature. The balancing method includes determining an imbalance of the anode; heating liquefy balancing material; dislocating the balancing material inside the balancing cavity to compensate the imbalance; and cooling to solidify the balancing material.
