摘要： Disclosed is an X-ray tube having an electron source and anode disposed therein. The anode includes a target surface positioned to receive electrons emitted by the electron source. A thermal structure is interfaced directly with the anode. The thermal structure defines a fluid passageway that is configured to receive and circulate a coolant. A thermally conductive porous matrix is disposed within the fluid passageway so as to facilitate the transfer of heat generated at the target surface to the coolant.

摘要： An imaging module includes a plurality of cathodes and respective gates, each cathode configured to generate a separate beam of electrons directed across a vacuum chamber and each gate matched to at least one respective cathode to enable and disable each separate beam of electrons from being directed across the vacuum chamber. A target anode is fixed within the vacuum chamber and arranged to receive the separate beam of electrons from each of the plurality of cathodes and, therefrom, generate a beam of x-rays. A deflection system is arranged between the plurality of cathodes and the target anode to generate a variable magnetic field to control a path followed by each of the separate beams of electrons to the target anode.

摘要： A compact source for high brightness x-ray generation is disclosed. The higher brightness is achieved through electron beam bombardment of multiple regions aligned with each other to achieve a linear accumulation of x-rays. This may be achieved by aligning discrete x-ray sub-sources, or through the use of x-ray targets that comprise microstructures of x-ray generating materials fabricated in close thermal contact with a substrate with high thermal conductivity. This allows heat to be more efficiently drawn out of the x-ray generating material, and in turn allows bombardment of the x-ray generating material with higher electron density and/or higher energy electrons, leading to greater x-ray brightness. The orientation of the microstructures allows the use of an on-axis collection angle, allowing the accumulation of x-rays from several microstructures to be aligned to appear to have a single origin, also known as “zero-angle” x-ray radiation.

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 installed in the cooling system 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 port is closed, and the service kit may be disconnected from the service port.

摘要： In a radiation generating apparatus of the invention, a radiation tube having a cathode for emitting an electron and an anode for generating a radiation by an irradiation of the electron emitted from the cathode is enclosed in a housing container filled with an insulating liquid. The apparatus has a mechanism in which a voltage for allowing the insulating liquid to flow can be applied between the cathode and the anode in a state where the cathode does not emit any electron. Even when the generation of the radiation is stopped, the insulating liquid can be efficiently sufficiently cooled without providing mechanical stirring means, and a high reliability is obtained even for intermittent use.
