    Abstract: An x-ray tube has a stationary cathode and a rotating anode in a vacuum housing. The anode is positioned on a housing-fixed axle such that it can be rotated, and is fashioned as a hollow body in the interior of which an axle-fixed ring projection is disposed, such that, at least between an inner surface of the rotating anode and the adjacent outer surface of the ring projection, a gap exists that is filled with liquid metal and forms a liquid-metal fluid bearing for the rotating anode.

    Abstract: A system and method for improving cooling of a heat-generating component in a closed-loop cooling system is shown. The system comprises a venturi having a throat which is coupled to an expansion tank that is exposed to atmospheric pressure in the embodiment being described. The venturi, when used with a pressure switch, can operate to determine a flow rate which can be used to generate a signal which in turn is used to activate or deactivate one or more of the components, such as the heat-generating component, in the system. Advantageously, the design of the embodiment described has a convenient system which utilizes a pressure switch, thereby eliminating the need for a differential pressure switch of the type used in the past.

    Abstract: An x-ray tube assembly (16) includes a vacuum envelope (52) and an x-ray permeable exit window (54). An anode (50) is positioned within the vacuum envelope (52) such that a near side is adjacent to the exit window (54) and a far side is opposite thereof. A cathode assembly (74) is also mounted within the vacuum envelope (52) which directs an electron beam (78) toward a focal spot or point (58) on the far side of the anode (50). The anode further includes a central cavity or indentation (70) which provides a location for mounting a set of radiation attenuating vanes (64) in addition to a shaped x-ray filter or compensator (68). Close placement of the vanes (64) and the filter (68) relative to the focal spot of the anode desirably reduce off focal radiation and allow beam shaping. An externally located collimator (18) further shapes the output x-ray beam.

    Abstract: An x-ray system comprising an x-ray generating device having improved heat dissipation capabilities is disclosed. The x-ray generating device comprises an x-ray tube mounted in a casing holding a circulating, cooling medium. According to the present invention, the x-ray generating device comprises a support mechanism mounted within said x-ray generating device in a manner for adjustably positioning, relative to the casing, the focal spot alignment path of generated x-rays. Additionally, the x-ray generating device comprises a cooling mechanism comprising an inlet chamber for channeling the cooling medium within said support mechanism. Additionally, a cooling stem may be positioned with the inlet chamber to increase the heat exchange surface area exposed to the cooling medium. Thus, the present invention advantageously increases the heat dissipation capability of the x-ray generating device.
