Abstract: A system for cooling an X-ray tube in a CT machine comprising a heat sink for drawing heat away from the X-ray tube and a collimator connected to the heat sink and adapted to collimate the X-rays emitted by the X-ray tube and “focus” those X-rays on an X-ray detector, the heat sink body being formed out of the same material as the emitter of the X-ray tube, such that the emitter opening of the X-ray tube will remain aligned with both the heat sink window and the collimator opening even when the emitter of the X-ray tube undergoes thermal expansion.

Abstract: A system and method for collecting backscattered electrons within a substantially evacuated vessel containing both an electron-emitting cathode assembly and an electron-attracting anode assembly. The system and method comprises an electron collector assembly including a first plate, a second plate, an internal member, a fluid inlet, and a fluid outlet. The first plate is mounted within the vessel closest to the anode assembly. The second plate is mounted within the vessel closest to the cathode assembly. The internal member is positioned between the first plate and the second plate, and includes an internal conduit for conveying a heat absorbing cooling fluid therethrough.

Abstract: An x-ray tube having one or more components, such as the rotor, that include a coating of relatively high emissivity. The coating, a metal oxide composition for example, is selectively applied to desired portions of the component by plasma spray or similar process. The relatively high emissivity of the coating enhances the ability of the coated surface to radiate heat, and thereby aids in implementation of a cooling effect with respect to the x-ray tube.
