PROBLEM TO BE SOLVED: To provide an x-ray target, a method of using the x-ray target, and a computer program product including instructions for carrying out a method of using the x-ray target.SOLUTION: An x-ray target of the present invention includes a substrate made from a soft x-ray producing material, and a high aspect ratio structure made from a hard x-ray producing material. The hard x-ray producing material is embedded in the substrate, formed on the substrate, cantilevered out from the edge of the substrate, or any combination thereof. The high aspect ratio structure comprises a plurality of high aspect ratio structures arranged in one or more grids or arrays, and the high aspect ratio structures in one of the one or more grids or arrays are arranged to form a Hadamard matrix structure. |
