Abstract: An X-ray inspection system for scanning items is provided. The system includes: a stationary X-ray source extending around a rectangular scanning volume, and defining multiple source points from which X-rays can be directed through the scanning volume; an X-ray detector array also extending around the rectangular scanning volume and arranged to detect X-rays from the source points which have passed through the scanning volume; a conveyor arranged to convey the items through the scanning volume; and at least one processor for processing the detected X-rays to produce scanning images of the items.

Abstract: An apparatus for detecting constituents in a sample includes first and second drift tubes defining first and second drift regions, and a controllable electric field device within a fragmentation region coupled to the first and second drift tubes. The apparatus also includes a first ion shutter positioned between the first drift and fragmentation regions. The apparatus further includes a control system configured to regulate the first ion shutter, thereby facilitating injection of a selected portion of ions from the first drift region into the fragmentation region. The control system is also configured to regulate the controllable device to modify the selected portion of ions to generate predetermined ion fragments within the fragmentation region, thereby facilitating injection of a selected portion of the predetermined fragmented ions into the second drift region. A method of detecting constituents in a sample is facilitated through such an apparatus.

Abstract: The present specification discloses systems and methods for identifying and reporting contents of a tanker, container or vehicle. Programmatic tools are provided to assist an operator in analyzing contents of a tanker, container or vehicle. Manifest data is automatically imported into the system for each shipment, thereby helping security personnel to quickly determine container contents. In case of a mismatch between container contents shown by manifest data and the contents as ascertained from the scanning system, the container or vehicle may be withheld for further inspection.

Abstract: The present specification describes a scanning/inspection system configured as a dual-view system using dual-energy sensitive stacked detectors that are partially populated with multi-energy discriminating detectors for overall enhanced energy resolution and therefore improved discrimination of materials through better estimation of material physical properties such as density and effective atomic number.

Abstract: The present specification describes an improved multi-energy radiation detector. In one embodiment, the signal generated by the detection medium is converted to digital form directly at the point of signal collection. This avoids the need for power intensive high bandwidth amplifiers and analog-to-digital converters, as it integrates the sensing device and signal processing onto the same silicon substrate to reduce the number of components in the system. In one embodiment, a single photon avalanche diode (SPAD) is coupled directly to a threshold detector to achieve an intrinsically low power and low noise detector.

Abstract: This specification describes an anode for an X-ray tube with multiple channels, where each channel defines an electron aperture through which electrons from a source pass to strike a target and a collimating aperture through which X-rays produced at the target pass out of the anode as a collimated beam. At least a portion of the walls of each channel are lined with an electron absorbing material for absorbing any electrons straying from a predefined trajectory. The electron absorbing material has a low atomic number, high melting point and is stable in vacuum. Graphite may be used as the electron absorbing material.

Abstract: A dual energy based X-ray scanning system has a linear detector array with high and low energy detectors. A signal processing method is employed that accounts for varying angles at which the transmitted X-rays impinge upon the detectors and also the varying order in which the transmitted X-rays pass through the high and low energy detectors. This yields both high resolution in the generated images and better penetration performance.

Abstract: The present specification discloses a radiographic inspection system for screening an area. The inspection system has a container that defines an enclosed volume, a radiation source positioned within the enclosed volume, a detector array, a movable structure attached to a portion of the base of the container, and a controller programmed to move the movable structure to achieve an optimum height of the radiation source's field of view based upon a plurality of data.
