摘要： A shield structure and focal spot control assembly is provided for use in connection with an x-ray device that includes an anode and cathode disposed in a vacuum enclosure in a spaced apart arrangement so that a target surface of the anode is positioned to receive electrons emitted by the cathode. The shield structure is configured to be interposed between the anode and the cathode and includes an interior surface that defines an aperture or other opening through which the electrons are passed from the cathode to the target surface of the anode. Additionally, fluid passageways defined in connection with the shield structure enable cooling of the shield structure. Finally, a magnetic device disposed proximate the cathode facilitates control of the location of the focal spot on the target surface of the anode.

摘要： An x-ray tube (1) includes a heat shield (130) which intercepts heat radiating from an anode (10), thereby reducing the temperature of a bearing assembly (62). The heat shield includes outer and inner concentric cylinders (132, 134) spaced from each other by a vacuum gap (138). The heat shield and a stationary portion (114) of the bearing assembly are both connected to a cold plate (150) so that heat is not conducted from the cylinders to the bearing assembly but is instead carried away by the cold plate to the surrounding cooling oil.

摘要： An x-ray tube electron shield is disclosed for interposition between an electron emitter and an anode configured to receive the emitted electrons. The electron shield is configured to withstand the elevated levels of heat produced by electrons backscattered from the anode and incident on the electron shield. This in turn equates to a reduced incidence of failure in the electron shield. In one embodiment the electron shield includes a body that defines a bowl-shaped aperture having a narrowed throat segment. The body of the electron shield includes a first body portion, a second body portion, and a disk portion. These portions cooperate to define the bowl and the throat segment. The throat segment and the lower portion of the bowl are composed of a refractory material and correspond with the regions of the electron shield that are impacted by relatively more backscattered electrons from the anode surface.
