摘要： The present specification discloses a covert mobile inspection vehicle with a backscatter X-ray scanning system that has an X-ray source and detectors for obtaining a radiographic image of an object outside the vehicle. The systems preferably include at least one sensor for determining a distance from at least one of the detectors to points on the surface of the object being scanned, a processor for processing the obtained radiographic image by using the determined distance of the object to obtain an atomic number of each material contained in the object, and one or more sensors to obtain surveillance data from a predefined area surrounding the vehicle.

摘要： In embodiments, the present invention describes the use of three-dimensional (3D) stationary gantry X-ray computed tomography systems to scan animals/livestock for enabling improved management of animal farming processes, functions or events. The present invention also discloses the use of 3D stationary gantry X-ray computed tomography systems for carcass screening and improved abattoir production planning, execution, and automation. In various embodiments, use of the scanning technology supports high throughput, automated, meat-processing lines with reduced manual labor, objectively measured product quality and improved food safety standards. In embodiments, the present specification discloses the use of 3D X-ray inspection to generate an image of an entire carcass and sections of the carcass, during the stages of dissection, final product preparation, and packaging of the carcass.

摘要： The present specification discloses a high speed scanning system for scanning cargo carried by rail. The system uses of a two-dimensional X-ray sensor array with, in one embodiment, a cone-beam X-ray geometry. The pulse rate of X-ray source is modulated based on the speed of the moving cargo to allow a distance travelled by the cargo between X-ray pulses to be equal to the width of the detector, for a single energy source, and to half the width of the detector for a dual energy source. This ensures precise timing between the X-ray exposure and the speed of the passing object, and thus accurate scanning of cargo even at high speeds.

摘要： An X-ray imaging inspection system for inspecting items comprises an X-ray source 10 extending around an imaging volume 16, and defining a plurality of source points 14 from which X-rays can be directed through the imaging volume. An X-ray detector array 12 also extends around the imaging volume 16 and is arranged to detect X-rays from the source points which have passed through the imaging volume, and to produce output signals dependent on the detected X-rays. A conveyor 20 is arranged to convey the items through the imaging volume 16.

摘要： 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.

摘要： 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.
