摘要： An x-ray system with an x-ray generating device having improved heat dissipation capabilities. The x-ray generating device includes an x-ray tube mounted in a casing holding a circulating, cooling medium. According to the present invention, the x-ray generating device includes a support mechanism mounted within the 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 includes a cooling mechanism having an inlet chamber for channeling the cooling medium within the support mechanism. Additionally, a cooling stem may be positioned within 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.

摘要： An imaging tube coolant volume control system (14) for an imaging tube (18) includes a compensation tank (80) that is configured to fluidically couple an imaging tube cooling circuit (11). The compensation tank (80) includes a cooling fluid (17) and a compensation-dividing member (100). The member (100) is adjustable in response to the change in volume of the cooling fluid (17). An overflow vessel (82) is fluidically coupled to the compensation tank (80). A compensation valve (86) is coupled between the compensation tank (80) and the overflow vessel (82) and allows flow of the cooling fluid between the compensation tank (80) and the overflow vessel (82) when pressure of the cooling fluid (17) is greater than or equal to a first predetermined pressure level.

摘要： A connector between an x-ray tube and high voltage source. An epoxy-filled housing is connected to the casing or housing of an x-ray tube or vacuum vessel. A high conductivity silicone gasket is positioned between the ceramic insulator of the x-ray tube and the epoxy material in the housing. Air is evacuated in the joint between the connector housing and x-ray tube vessel and a vacuum created therein. Appropriate seals are positioned maintaining the integrity of the vacuum. Spring-loaded attachment bolts are also utilized to secure the connector housing and vacuum vessel casing together.

摘要： An x-ray transmissive window assembly for use in metal framed x-ray tubes is formed of at least two layers of metal joined by explosion welding. An x-ray transmissive window, preferably comprising aluminum or an aluminum alloy, is joined to a transition layer, which is typically the same material as the x-ray tube vacuum vessel, to form the transmissive window assembly. The transmissive window is formed in the assembly by removing the transition layer material from the central region. A weld flange is prepared by removing the x-ray transmissive window material from the periphery of the assembly. The assembly is then welded into the x-ray tube vacuum vessel using traditional techniques. In another embodiment, a multi-layered window assembly comprises an x-ray transmissive window, a transition layer weldable to an x-ray tube vacuum vessel, and an intermediate layer that acts as a mask or aperture to attenuate peripheral radiation and clearly define the edges of the transmitted x-ray beam. The intermediate layer also acts as a diffusion barrier that prevents the formation of a brittle intermetallic layer between the transmissive window and transition layers during high temperature operation. Additionally, according to the present invention, an x-ray system comprising the above-described window assembly is disclosed.
