ABSTRACT:
An x-ray tube (10) includes an anode (14) connected to a mechanical drive (36). The mechanical drive oscillates the anode in a gyrating motion relative to a body of the x-ray tube. The mechanical drive is operatively connected to the anode via a bellows assembly (16) and is capable of rocking the anode in two axes simultaneously. The preferred anode is shaped in a shperical section (28) providing a fixed focal distance between the anode and a cathode (20) regardless of relative position of the anode within the body. An electron shield (40) is disposed between the cathode and the anode and has an opening along a preferred path for electron travel. Improved heat exchange is provided by applying a heat transfer agent to an obverse side of the anode which is preferably located outside of a vacuum envelope (18) defined by the x-ray tube body, the anode, and the bellows.
