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.

X-ray tube cooling systems. In one example embodiment, an x-ray tube includes a housing, a window frame attached to the housing, and a window attached to the window frame. The housing defines an aperture through which electrons can pass from a cathode to an anode. The housing also defines an inlet port and an outlet port. The window frame defines an opening through which x-rays can pass. The window covers the opening defined by the window frame. The housing and the window frame are configured such that a liquid can flow from the inlet port to the outlet port through either a first liquid path at least partially defined by the housing or a second liquid path cooperatively defined by the housing and the window frame. The second liquid path is disposed about at least a portion of the opening in the window frame.
