摘要： A cathode assembly including certain features designed to protect the integrity of a filament contained therein is disclosed. In particular, the cathode assembly is configured to prevent damage to the filament should it inadvertently contact another portion of the cathode assembly. In an example embodiment, an x-ray tube incorporating features of the present invention is disclosed. The x-ray tube includes an evacuated enclosure containing a cathode assembly and an anode. The cathode assembly includes a head portion having a head surface. A slot is defined on the head surface and an electron-emitting filament is included in the slot. A protective surface is defined on the head surface proximate to a central portion of the filament. The protective surface in one embodiment is composed of tungsten and is configure to prevent fusing of the filament to the protective surface should the filament inadvertently contact the protective surface.

摘要： An x-ray imaging system is disclosed, where one example of such a system includes a frame or other structure to which a modular cooling unit of the x-ray imaging system is attached. The modular cooling unit includes a radiator, configured for fluid communication with an x-ray tube housing, as well as one or more fans configured to cause a flow of air to pass through the radiator. In this example, the x-ray imaging system further includes a detector array arranged to receive x-rays generated by an x-ray tube insert disposed within the x-ray tube housing. In operation, the air flow caused by the fans of the modular cooling unit removes heat from coolant flowing out of the x-ray tube housing and through the radiator.
