In one example, an x-ray tube includes an evacuated enclosure and an anode disposed with the evacuated enclosure. The anode is configured to receive electrons emitted by an electron emitter. The x-ray tube also includes an evacuated enclosure window disposed within a port of the evacuated enclosure. The evacuated enclosure window includes first and second axes, the first axis being relatively shorter than the second axis. The x-ray tube also includes means for directing coolant flow. The means for directing coolant flow causes coolant to flow across an exterior surface of the evacuated enclosure window in a direction substantially parallel to the first axis.
