Abstract

An X-ray tube (100) for X-ray imaging is described. The X-ray tube comprises an anode (10) configured to rotate around a rotational axis (12); a cathode (20) configured to generate an electron beam (14) impinging the anode; a rotational system (30) for rotating the anode around the rotational axis, wherein the rotational system comprises a bearing having a rotatable part and a stationary part. The rotatable part of the bearing is attached to the anode. The X-ray tube further includes a vacuum frame (40) enclosing the anode and the cathode, and a mechanical interface (50). The mechanical interface is positioned between the bearing and the vacuum frame, and is mechanically connecting the stationary part of the bearing and the vacuum frame. The mechanical interface comprises at least three elastic elements at different positions around the rotational axis, wherein each elastic element extends along the rotational axis to provide stiffness in an axial direction of the rotational axis, and wherein each elastic element is bendable in a radial direction of the anode.
