Integrated actuator means for performing translational and / or rotational displacement movements of at least one X-ray radiation radiating the focal spot of the anode relative to a fixed reference position; and a resulting parallel and X-ray diagnostic system comprising means for compensating for angle shifts

摘要

X-ray systems for use in high-resolution imaging applications with an improved power rating are provided. An X-ray source comprises at least one integrated actuator unit (206, 206, 206a or 206b) for performing at least one translational and/or rotational displacement by moving the position of the X-ray source's anode (204, 204, 204a or 204b) relative to a stationary reference position. This helps to overcome power limitations due to an overheating of the anode at its focal ̂spot position (205). In addition to that, a focusing unit (203) for allowing an adapted focusing of the anode's focal spot (205) which compensates deviations in the focal spot size resulting from said anode displacements and/or a deflection means (211, 21 Ia or 21 Ib) for generating an electric and/or magnetic field deflecting the electron beam (202, 202a or 202b) in a direction opposite to the direction of the rotary anode's displacement movement may be provided.
