Abstract
Systems and methods are provided for improving thermal management strategies of a cathode assembly of an X-ray tube. In one embodiment, an X-ray tube comprises an anode assembly and a cathode assembly, wherein the cathode assembly includes one or more elements that include an internal porous section for controlling a flow of heat within the cathode assembly during operation of the X-ray tube. In this way, heat conduction to temperature sensitive aspects of the cathode assembly may be reduced, while enabling sufficient heat transfer to other parts of the cathode assembly to minimize deformation.
