摘要： An X-ray tube has a cathode, an anode target to emit X-rays, and a vacuum envelope which houses the cathode and the anode target. The vacuum envelope has a first metal member connected to the anode target, a second metal member which is connected to the first metal member and has a coefficient of thermal expansion lower than that of the first metal member, and an electrically insulating annular ceramic member connected to the second metal member and the cathode. In addition, the X-ray tube has a cooling system which is connected to the first metal member and forms a cooling passage. Furthermore, the X-ray tube has an adapter which is in contact with the first metal member, surrounds the second metal member and has a thermal conductivity higher than that of the second metal member, and a heat-transfer medium placed between the ceramic member and the adapter.

摘要： A distributed X-ray source (3) and an imaging system (1) comprising such an X-ray source (3) are proposed. The X-ray source (3) comprises an electron beam source arrangement (19) and an anode arrangement (17). The electron beam source arrangement (19) is adapted to emit electron beams (24) towards at least two locally distinct focal spots (27) on the anode arrangement (17). Therein, the X-ray source is adapted for displacing the anode arrangement (17) with respect to the electron beam source arrangement (19). While the provision of a plurality of focal spots allows acquisition of projection images under different projection angles thereby allowing reconstruction of three-dimensional X-ray images e.g. in tomosynthesis application, a displacement motion of the anode arrangement (17) with respect to the electron beam source arrangement (19) may allow for distributed heat flux to the anode arrangement thereby possibly reducing cooling requirements.

摘要： An x-ray target pedestal assembly and a method of protecting the x-ray target from breaking down as a result of the extreme heat that is produced when an electron beam is aimed at the target to produce x-rays. The target is submerged in cooling fluid and is rotated by a constant flow of the cooling fluid over and around the target in order to dissipate heat. The fluid is guided by integrated flow diverters in the target cover. The target may also be protectively coated either in its entirety or along the electron beam path in order to further protect it from the heat of the electron beam impact or from breakdown as a result of attack of free radicals or other chemically reactive components of the cooling fluid which are produced in the extreme target environment.

摘要： The present invention provides an electrode, typically an anode, for use in an x-ray generating apparatus comprising an electron source. The electrode comprises a housing, a diamond member mounted to the housing, and a target located on the diamond member, which target in use is bombarded with electrons from the electron source so as to generate x-rays. A bonding layer is located between the housing the diamond member, which bonding layer comprises an alloy having a solidus or melting point of less than 900° C. A particularly preferred alloy comprises silver, copper and indium. This arrangement assists in dissipating heat generated at the electrode surface whilst retaining the structural integrity of the electrode.

摘要： The invention describes an X-ray source in which a cooling plate (36) for water-cooling the anode (28) of an X-ray tube (26) is firmly mounted on a radiation protection casing (20) and the X-ray tube (26) is rotatably borne relative to the cooling plate (36) in the radiation protection casing (20). The cooling plate (36) and X-ray tube (26) have small axial play with respect to each other, which allows for rotation. Radial seals (R1, R2) ensure adequate sealing of the cooling water throughout the entire axial play. Advantageously, a sealing plate (27) for adaptation to the cooling plate (36) is attached to the X-ray tube (25). With the X-ray source in accordance with the invention, it is easy to switch between various focus types in one casing structure.

Furthermore, the second plate additionally has an internal conduit for conveying a heat-absorbing fluid within. Both the fluid inlet and the fluid outlet are in fluid communication with the conduit in the second plate. During operation, the structure is able to attract scattered electrons and transfer thermal energy attributable to the electrons away from the structure.
