ANGLE-DEPENDENT X-RAY DIFFRACTION IMAGING SYSTEM AND METHOD OF OPERATING THE SAME
First Claim
1. An x-ray diffraction imaging (XDI) system having a system axis, said system comprising:
- at least one x-ray source configured to generate x-rays directed toward an object that includes at least one substance, wherein said at least one x-ray source is further configured to irradiate at least one voxel defined within the object with x-rays arriving from a plurality of directions, each direction defined by an angle of incidence with respect to the system axis;
at least one detector configured to detect scattered x-rays after the x-rays have passed through the object; and
at least one processor coupled to said at least one detector, said at least one processor programmed to generate a plurality of XDI profiles of the object voxel, wherein each XDI profile is a function of an associated angle of incidence.

Abstract
An x-ray diffraction imaging (XDI) system having a system axis includes at least one x-ray source configured to generate x-rays directed toward an object that includes at least one substance. The at least one x-ray source is further configured to irradiate at least one voxel defined within the object with x-rays arriving from a plurality of directions, each direction defined by an angle of incidence with respect to the system axis. The system also includes at least one detector configured to detect scattered x-rays after the x-rays have passed through the object. The system further includes at least one processor coupled to the at least one detector. The processor is programmed to generate a plurality of XDI profiles of the object voxel. Each XDI profile is a function of an associated angle of incidence.

11. One or more non-transitory computer-readable storage media having computer-executable instructions embodied thereon, wherein when executed by at least one processor, the computer-executable instructions cause the processor to:
-
generate a plurality of XDI profiles of an object voxel, wherein the object voxel is irradiated with x-rays directed toward an object that includes at least one substance, the x-rays having a plurality of angles of incidence, each XDI profile a function of an associated angle of incidence, each angle of incidence defined with respect to a system axis; compare the plurality of XDI profiles; and discriminate the irradiated object as one of a potential threat and a potential non-threat as a function of comparison of the plurality of XDI profiles. - View Dependent Claims (12, 13, 14, 15)
