Abstract

A shield structure (200) and focal spot control assembly (250) is provided for use in connection with an X-ray device (100) that includes an anode (114) and cathode (112)disposed in a vacuum enclosure (102) in a spaced apart arrangement so that a target surfac of the anode is positioned to receive electrons emitted by the anode.
