Abstract: A multi-region target that is configured to selectively generate two different energy distributions when exposed to an excitation electron beam is described. The multi-region target includes multiple regions with different x-ray generating characteristics. Thus, the interaction between an excitation electron beam and the target generates an x-ray beam with an energy distribution that depends upon which target region is exposed to the excitation electron beam. The different x-ray spectra may be used to produce an enhanced contrast x-ray image. A method of detecting the rotational position of the multi-region target based upon the contrast level of the resulting images also is described.

Abstract: An energy converter unit and X-ray source system are presented. The energy converter unit comprises a multilayered crystal structure having a selected layers' arrangement comprising at least first and second of layers of at least first and second material compositions. The layers-arrangement is formed of a pattern of n1 layers of said first layer type and n2 layers of said second layer type generating a selected lattice periodicity of said layers. The lattice periodicity is selected such that said multilayered crystal structure responds to the charged particle beam of predetermined parameters by coherent emission of X-ray radiation having selected spectral content and emission direction.

Abstract: The disclosed subject matter includes devices and methods relating to anode assemblies and/or X-ray assemblies. In some aspects, a method of forming an X-ray assembly may include providing an anode base formed of a first material and including a first end. The method may include depositing a second material different from the first material over a first surface of the anode base to form a coated portion of the anode base. The coated portion may be configured such that some backscattered electrons do not travel beyond the coated portion.
