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.
Claims15
An x-ray tube, comprising:
- 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, and a cathode cup assembly that includes at least a cup plate with a cup section, a ceramic plate, and an emitter weld pad for securing one or more emitters to the cathode assembly.
A cathode cup assembly for an x-ray tube, comprising:
- one or more emitters;
- an emitter weld pad;
- a ceramic plate;
- a cup plate that includes a cup section, the ceramic plate positioned between the emitter weld pad and the cup plate, and where the cup section extends through an orifice of the ceramic plate;
- and
- wherein at least a portion of the cup section and at least a portion of the emitter weld pad each include an internal porous section for thermal management of the cathode cup assembly.
