Abstract: 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.

Abstract: 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.

Abstract: System and method for XRD-based false alarm resolution in computed tomography (“CT”) threat detection systems. Following a scan of an object with a megavoltage CT-based threat detection system, a suspicious area in the object is identified. The three dimensional position of the suspicious area is used to determine a ray path for the XRD-based threat detection system that provides minimal X-ray attenuation. The object is then positioned for XRD scanning of the suspicious area along this determined ray path. The XRD-based threat detection system is configured to detect high density metals (“HDMs) as well as shielded Special Nuclear Materials (“SNMs”) based on cubic or non-cubic diffraction profiles.
