摘要： For X-ray tubes of the rotary-anode type for generating a fan beam of X-rays, compensation is afforded for system-related disturbances of the focal spot position on a target area of the rotating anode, and particularly for the anode wobble in an X-ray tube, which occurs as a periodically wobbling inclination angle of the anode disk's rotational plane with respect to an ideal rotational plane, the latter being oriented normal to the rotational axis of the rotary shaft on which the anode disk is inclinedly mounted due to an inaccuracy during its production process. For this purpose, the electron beam generated by a thermionic or other type of electron emitter of the tube's cathode and thus the focal spot position on a target area of the anode disk's X-ray generating surface are steered such that the focal spot stays within the plane of the central X-ray fan beam.
