Abstract: A method for manufacturing x-ray tube parts is disclosed wherein metallic pieces are explosively bonded together to establish a high strength, stable union between them. The x-ray tube parts may then be milled from the bonded metallic pieces. The explosion bonding process creates only discrete intermetallic components in the joint region instead of a continuous, weakening intermetallic layer common in brazed joints. An explosion bond joint is characterized by a wavelike interface, thereby increasing surface area over which the components are bonded and further increasing bond integrity. Stems, rotor hubs, rotor sleeves, anodes, and other tube components may be manufactured using this method.

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.

Abstract: An x-ray tube has a cathode and an anode which are arranged in a vacuum housing, with an electromagnet for deflecting the electron beam traveling from the cathode to the anode. This electromagnet is formed by a C-shaped yoke with two legs that are connected to each other by a base section surrounded by a winding. Respective pole shoes with opposing pole faces are disposed at the ends of the legs. The electron beam passes between the two pole shoes as it propagates from the cathode to the anode. Each pole face has a width which does not exceed the width of its pole shoe.
