Abstract
A liquid-cooled aperture body in an x-ray tube. In one example embodiment, an x-ray tube is configured to be at least partially submerged in a liquid coolant. The x-ray tube includes a cathode at least partially positioned within a cathode housing, an anode at least partially positioned within a can, and an aperture body coupling the cathode housing to the can. The can is formed from a first material and the aperture body is formed from a second material. The aperture body defines an aperture through which electrons may pass between the cathode and the anode. The aperture body further defines at least two exterior surfaces that are each configured to be exposed to the liquid coolant in which the x-ray tube is at least partially submerged.
