    摘要： A monolithic housing for an x-ray source can wrap at least partially around a power supply and an x-ray tube. The monolithic housing can include Al, Ca, Cu, Fe, Mg, Mn, Ni, Si, Sr, Zn, or combinations thereof. Mg can be a major component of the monolithic housing. The monolithic housing can be formed by injection molding. The monolithic housing can provide one or more of the following advantages: (a) light weight (for easier transport), (b) high electrical conductivity (to protect the user from electrical shock), (c) high thermal conductivity (to remove heat generated during use), (d) corrosion resistance, (e) high strength, and (f) high electromagnetic interference shielding (to shield power supply components from external noise, to shield other electronic components from power supply noise, or both).

    摘要： A modular X-ray source and method for replacement of such an X-ray source are disclosed. The source is inside a consumable modular enclosure where the entire assembly is swapped out during maintenance. The enclosure covers an X-ray tube, high voltage circuit boards 6 and cooling insulating oil are arranged inside the module enclosure. The enclosure structure includes an X-ray window, connector engagement alignment guide and electrical connectors. The modular X-ray source is used in a multiple source tomosynthesis imaging system where multiple pulsed X-ray sources are utilized. The easy replacement of X-ray tube assembly inside the consumable modular enclosure results in lower maintenance cost and overall reliable X-ray imaging machine. The modular source has potential to increase the machine volume in the field and create new standards for replaceable modular X-ray source.

    摘要： A shield around an x-ray tube, a voltage multiplier, or both can improve the manufacturing process by allowing testing earlier in the process and by providing a holder for liquid potting material. The shield can also improve voltage standoff. A shielded x-ray tube can be electrically coupled to a shielded power supply.

    摘要： An apparatus is provided, which includes a source, a holder, and a conductive member. The source generates an electron beam and the holder is configured to receive a sample. The conductive member is arranged between the source and the holder at a first position or a second position. The electron beam impinges on the sample to provide a first analysis reading when the conductive member is at the first position, and the electron beam impinges on the conductive member to emanate an X-ray beam on the sample to provide a second analysis reading when the conductive member is at the second position.

    摘要： An X-ray generator includes an X-ray tube, an X-ray tube accommodation portion, and a power source unit having an internal substrate supplying a voltage to the X-ray tube sealed inside an insulating block. Insulating oil is enclosed in a space defined by an upper surface of the insulating block and an inner surface of the X-ray tube accommodation portion. A high-voltage power supply unit connected to a target support portion is disposed on the upper surface. At least one protrusion portion protruding to an insulating valve side beyond a boundary portion where the high-voltage power supply unit, the upper surface, and the insulating oil meet and surrounding the high-voltage power supply unit is provided on the upper surface. An apex portion of the protrusion portion is separated from an imaginary plane including an end portion of the insulating valve and extending in a direction orthogonal to a tube axis.
