ABSTRACT:
A method to account for cross-talk among a plurality of coherent scatter detectors of a multi-detector inverse fan beam x-ray diffraction imaging (MD-IFB XDI) system. The MD-IFB XDI system includes a multi-focus x-ray source (MFXS) that emits radiation sequentially from a plurality of focus points denoted by F1, F2, . . . Fnwith a running index i. The method includes measuring a diffraction profile Xkfor each coherent scatter detector Dkof the plurality of coherent scatter detectors. The diffraction profile includes a spectrum of a number of photons measured in a plurality of corresponding coherent scatter detectors. Each coherent scatter detector Dkis corrected to remove scatter from a plurality of primary beams directed to remaining coherent scatter detectors of the plurality of coherent scatter detectors.
