Abstract (en)
[origin: WO2006029026A2] 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.
