Abstract: Strain matching of crystals and horizontally-spaced monochromator and analyzer crystal arrays in diffraction enhanced imaging systems and related methods are disclosed. A DEI system, including strain matched crystals can comprise an X-ray source configured to generate a first X-ray beam. A first monochromator crystal can be positioned to intercept the first X-ray beam for producing a second X-ray beam. A second monochromator crystal can be positioned to intercept the second X-ray beam to produce a third X-ray beam for transmission through an object. The second monochromator crystal has a thickness selected such that a mechanical strain on a side of the first monochromator crystal is the same as a mechanical strain on the second monochromator crystal. An analyzer crystal has a thickness selected such that a mechanical strain on a side of the first monochromator crystal is the same as a mechanical strain on the analyzer crystal.

Abstract: 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.

Abstract: In an x-ray system and a method for tomosynthetic scanning of a subject, x-ray radiation is emitted from two x-ray sources that are panned relative to the subject during a tomosynthetic scan. The two x-ray sources each emit an x-ray beam, the respective x-ray beams being parallel to each other with regard to their beam directions proceeding toward the subject. X-rays from the two parallel beams attenuated by the subject are detected by a two-dimensional x-ray detector, that is substantially stationary during the tomosynthetic scan.

Abstract: One or more components of an x-ray target assembly are manufactured using an electroforming process. The electroforming is carried out by providing an electroforming apparatus that includes an electrolyte, a metal anode, and an electrically conductive cathode. The cathode includes an intermediate x-ray target assembly upon which the metal is to be deposited and/or an electrically conductive mold for forming a component of an x-ray target assembly. The x-ray target component (e.g., a substrate or focal track) is formed by submersing the cathode in the electrolyte and applying a voltage across the anode and the cathode to cause the metal from the anode to be electroformed on the intermediate target and/or the mold. The electroforming is continued until a desired thickness of metal is achieved. The electroforming process can be used to manufacture an x-ray target substrate, focal track, stem, barrier, or other metal layer of the target assembly.

Abstract: An anode for an X-ray source is formed in two parts, a main part (18) and a collimating part (22). The main part (18) has the target region (20) formed on it. The two parts between them define an electron aperture (36) through which electrons pass reach the target region (20), and an X-ray aperture through which the X-rays produced at the target leave the anode. The anode produces at least the first stage of collimation of the X-ray beam produced.
