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 along a line relative to the subject during a tomosynthetic scan. The two x-ray sources are located next to each other along the line, and each emit an x-ray beam. 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: 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: A method for obtaining a concentrated, monochromatic x-ray beam from a standard x-ray tube or other source of polychromatic emission. X-rays from the anode of the x-ray tube fluoresce an adjoining, independent target that produces a monochromatic spectrum, a portion of which is focused by the x-ray optical system. This two-stage method gives the system considerably versatility without undue loss in signal. The two-stage concentrator makes practical the use of focusing optics in hand-held and portable instruments.

Abstract: An anode for an X-ray source is formed in two parts, a main part and a collimating part. The main part has the target region formed on it. The two parts between them define an electron aperture through which electrons pass to reach the target region, 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.

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.
