Abstract
An x-ray tube assembly includes a vacuum enclosure that includes a cathode portion, a target portion, and a throat portion having a plurality of recesses formed therein to break up eddy currents generated in the throat portion. The throat portion has an upstream end coupled to the cathode portion and a downstream end coupled to the target portion. The x-ray tube assembly also includes a target positioned within the target portion of the vacuum enclosure, and a cathode positioned within the cathode portion of the vacuum enclosure. The cathode is configured to emit a stream of electrons through the throat portion toward the target.
