Patent ID: 7856083

Claim:
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, said method comprising: emitting a plurality of primary beams simultaneously from an x-ray source, each primary beam of the plurality of primary beams is directed to a corresponding convergence point associated with a corresponding coherent scatter detector of the plurality of coherent scatter detectors, each primary beam is configured to interact with an object to produce a scatter radiation; measuring a diffraction profile X k at each coherent scatter detector D k of the plurality of coherent scatter detectors, each diffraction profile X k comprises a spectrum of a number of photons from the scatter radiation measured by the coherent scatter detector D k , wherein each diffraction X k includes a cross-talk component arising from at least the primary beam directed to the convergence point associated with at least a second of the plurality of coherent scatter detectors D j ; generating, for each of a plurality of energy levels within the spectrum measured in the diffraction profile X k , a correction factor for the cross-talk component based on the energy level and a scatter angle defined between the primary beam directed to the convergence point associated with the coherent scatter detector D j and a scatter radiation path from that primary beam to the coherent scatter detector D k ; and correcting each diffraction profile X k corresponding to each coherent scatter detector D k to remove the cross-talk component.
