Abstract: Fabrication of a multi-layer X-ray source is disclosed using bulk structures to fabricate a multi-layer target structure. In one implementation, layers of X-ray generating material, such as tungsten, are interleaved with thermally conductive layers, such as diamond layers. To prevent delamination of the layers, various mechanical, chemical, and/or structural approaches may also be employed.

Abstract: In various embodiments, a multi-layer X-ray source target is provided having two or more layers of target material at different depths and different thicknesses. In one such embodiment the X-ray generating layers increase in thickness in relationship to their depth relative to the electron beam facing surface of the source target, such that X-ray generating layer further from this surface are thick than X-ray generating layers closer to the electron beam facing surface.

Abstract: X-ray imaging systems are provided that include an X-ray source and an X-ray detector. A filtering device is positioned between the X-ray source and the X-ray detector and includes one or more micro-filters each adapted to transition between an X-ray filtering position and an X-ray non-filtering position. A controller is programmed to control operation of the micro-filters.

Abstract: Embodiments of the disclosure relate to electron emitters for use in conjunction with X-ray emitting devices. In certain embodiments the emitter includes features that prevent, limit, or control deflection of the electron emitter at operating temperatures. In this manner, the electron emitter may be kept substantially flat or at a desired curvature during operation.

Abstract: A multi-energy X-ray imaging system includes an X-ray source and an X-ray detector. A filtering device includes an X-ray translucent substrate having a plurality of septa disposed therein at a plurality of fixed positions with respect to the substrate. A controller is programmed to acquire a first set of projection data at a first energy spectrum by controlling the X-ray source to emit the X-rays at the first energy spectrum and controlling the position of the filtering device to focally align the plurality of septa with the X-ray beam emitted from the focal spot, and to acquire a second set of projection data at a second energy spectrum with a mean energy greater than the mean energy of the first energy spectrum by controlling the X-ray source to emit the X-rays at the second energy spectrum and controlling a change in the position of the filtering device to focally misalign the plurality of septa with the X-ray beam emitted from the focal spot.
