摘要： A primary collimator for a multiple inverse fan beam x-ray diffraction imaging (MIFB XDI) system. The MIFB XDI system includes a multi-focus x-ray source (MFXS) defining a plurality of focus points arranged along a length of the MFXS. Each focus point is sequentially activated to emit an x-ray fan beam including a plurality of primary beams each directed to a corresponding convergence point. The primary collimator includes a first diaphragm configured to be positioned with respect to the MFXS. The first diaphragm defines a plurality of first channels through a thickness of the first diaphragm. Each first channel is aligned with a corresponding focus point and configured to transmit the x-ray fan beam. A second diaphragm is positioned with respect to the first diaphragm and defines a plurality of second channels through a thickness of the second diaphragm. Each second channel is axially aligned with a corresponding first channel.

摘要： A detection system includes a multi-focus radiation source configured to generate X-ray radiation and a primary collimator defining a first row of apertures and a second row of apertures. The first row of apertures forms first X-ray beams within a first plane from the X-ray radiation, and the second row of apertures forms second X-ray beams within a second plane from the X-ray radiation. The first plane is different than the second plane. The detection system further includes a scatter detector including a first row of scatter detector elements and a second row of scatter detector elements. The first row of scatter detector elements is configured to detect scattered radiation from the first X-ray beams, and the second row of scatter detector elements is configured to detect scattered radiation from the second X-ray beams.

摘要： 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, . . . Fn with a running index i. The method includes measuring a diffraction profile Xk for each coherent scatter detector Dk of 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 Dk is corrected to remove scatter from a plurality of primary beams directed to remaining coherent scatter detectors of the plurality of coherent scatter detectors.

摘要： A contraband detection system includes a first contraband detection apparatus designed to perform a first scan on an object and a second contraband detection apparatus positioned in-line with the first contraband detection apparatus to perform a second scan on the object. A computer is included in the contraband detection system and is programmed to cause the first contraband detection apparatus to perform the first scan and acquire object data therefrom. The computer is further programmed to identify one or more regions of interest (ROI) in the object based on the object data, cause the second contraband detection apparatus to perform the second scan on the one or more identified ROIs, and acquire object data from the second scan.

摘要： A system and method for scanning objects using a non-translational x-ray diffraction (XRD) system is disclosed. The system includes a scanning area through which an object to be scanned traverses and a distributed x-ray source having a plurality of focal spot locations. The distributed x-ray source is affixed on the scanning area and is configured to emit x-rays towards the object as a series of parallel x-ray beams. A stationary detector arrangement is affixed on another side of the scanning area generally opposite the distributed x-ray source and is configured to measure a coherent scatter spectra of the x-rays after passing through the object. A data acquisition system (DAS) is connected to the detector arrangement and is configured to measure the coherent scatter spectra, which is utilized to generate XRD data and determine a material composition of at least a portion of the object from the XRD data.

摘要： An x-ray diffraction imaging device includes at least one x-ray detector and at least one scatter collimator positioned upstream of the at least one x-ray detector. The at least one collimator includes a plurality of successive plates. Each of the plurality of plates defines a plurality of rectangular holes. The plurality of successive plates are arranged such that the plurality of rectangular holes define a plurality of quadrilateral passages extending through the at least one scatter collimator. Each of the plurality of quadrilateral passages is configured to increase a rate of detection of first x-rays that define an x-ray transit path enclosed within a single such quadrilateral passage. Also, the plurality of quadrilateral passages is configured to decrease a rate of detection of second x-rays that define an x-ray transit path that intersects more than one such quadrilateral passage.
