摘要： An X-ray emitting target including a diamond substrate, a first layer disposed on the diamond substrate and including a first metal, and a second layer disposed on the first layer and including a second metal whose atomic number is 42 or more and which has a thermal conductivity higher than that of the first metal. Carbide of the first metal is present at a boundary between the diamond substrate and the first layer. The target is prevented from overheating, so that output variation due to rising temperature is suppressed. Thus it is possible to emit stable and high output X-rays.

摘要： Systems and methods for replacing coolant of an x-ray tube assembly having a closed cooling system include a service port that is operatively connected to a portion of the x-ray tube assembly and a vacuum assisted service kit that is operatively coupled to the service port. Used coolant is drained from the x-ray tube assembly, and thereafter a vacuum is drawn on the x-ray tube assembly via the service kit. Replacement coolant within a vacuum tank of the service kit is degassed under a vacuum. The degassed replacement coolant is provided into the cooling system from the vacuum tank, preferably by pushing under pressure with an inert gas to prevent the introduction of any air into the replacement coolant. The replacement coolant may be pressurized in the cooling system with the inert gas. Thereafter, the service kit may be disconnected from the service port.

摘要： The present invention relates to X-ray generating technology in general. Providing an electron collecting element of an X-ray generating device statically may allow for the manufacture of X-ray systems with reduced moving parts and actuating parts, possibly reducing manufacturing costs and sources for failure. Consequently, an electron collecting element with increased thermal loadability is presented. According to the present invention, an electron collecting element (28) is provided, comprising a surface element (22) and a heat conducting element (26). The heat conducting element (26) comprises a first thermal conductivity in a first direction and at least a second thermal conductivity in at least a second direction. The first thermal conductivity is greater than the second thermal conductivity. The first direction is substantially perpendicular to the surface element (22).

摘要： In one example, an x-ray tube includes an evacuated enclosure and an anode disposed with the evacuated enclosure. The anode is configured to receive electrons emitted by an electron emitter. The x-ray tube also includes an evacuated enclosure window disposed within a port of the evacuated enclosure. The evacuated enclosure window includes first and second axes, the first axis being relatively shorter than the second axis. The x-ray tube also includes means for directing coolant flow. The means for directing coolant flow causes coolant to flow across an exterior surface of the evacuated enclosure window in a direction substantially parallel to the first axis.
