<p>The present invention relates to an X-ray tube with an active balancing arrangement. In order to provide improved balancing for a minimized imbalance during operation, an X-ray tube (10) with an active balancing arrangement (12) is provided, comprising a rotating anode arrangement (14), a bearing arrangement (20, 22, 24), a driving arrangement (26, 28, 30) for rotating the anode arrangement, an imbalance detection arrangement (32), and active balancing means (34, 36, 38, 40, 42). The bearing arrangement is provided as a fixed bearing of the rotating anode arrangement for supporting the rotating anode arrangement. The imbalance detection arrangement is configured to detect an imbalance of the anode. The active balancing means are electro-magnetic balancing means configured to provide a magnetic field and to apply magnetic eccentricity forces to the rotating arrangement.</p> |
