Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a method and a device for determining the distribution of an X-ray fluorescence (XRF) marker (16) in a body volume (14). The body volume (14) is irradiated with a beam of rays (12) from an X-ray source (10) with a first ray component with a quantum energy just above and a second ray component with a quantum energy just below the K-edge of the XRF marker (16). Secondary radiation emitted from the body volume (14) is detected in a location-resolved way by a detector (30). To separate the X-ray fluorescence components in the secondary radiation from background radiation, the body volume is irradiated for a second time with a beam of rays from which the first ray component has been substantially removed by a filter (22) made from the material of the XRF marker.
