  • Patent number: 9618648
    Abstract: The present application discloses an X-ray scanner having an X-ray source arranged to emit X-rays from source points through an imaging volume. The scanner may further include an array of X-ray detectors which may be arranged around the imaging volume and may be arranged to output detector signals in response to the detection of X-rays. The scanner may further include a conveyor arranged to convey an object through the imaging volume in a scan direction, and may also include at least one processor arranged to process the detector signals to produce an image data set defining an image of the object. The image may have a resolution in the scan direction that is at least 90% as high as in one direction, and in some cases two directions, orthogonal to the scan direction.

  • Publication number: 20170023696
    Abstract: The present specification describes a compact, hand-held probe or device that uses the principle of X-ray backscatter to provide immediate feedback to an operator about the presence of scattering and absorbing materials, items or objects behind concealing barriers irradiated by ionizing radiation, such as X-rays. Feedback is provided in the form of a changing audible tone whereby the pitch or frequency of the tone varies depending on the type of scattering material, item or object. Additionally or alternatively, the operator obtains a visual scan image on a screen by scanning the beam around a suspect area or anomaly.

  • Publication number: 20170023698
    Abstract: 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 traveled 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.

  • Publication number: 20160343533
    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.

  • Patent number: 9442082
    Abstract: The present specification discloses an X-ray system for processing X-ray data to determine an identity of an object under inspection. The X-ray system includes an X-ray source for transmitting X-rays, where the X-rays have a range of energies, through the object, a detector array for detecting the transmitted X-rays, where each detector outputs a signal proportional to an amount of energy deposited at the detector by a detected X-ray, and at least one processor that reconstructs an image from the signal, where each pixel within the image represents an associated mass attenuation coefficient of the object under inspection at a specific point in space and for a specific energy level, fits each of pixel to a function to determine the mass attenuation coefficient of the object under inspection at the point in space; and uses the function to determine the identity of the object under inspection.

  • Publication number: 20160259067
    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.

  • Publication number: 20160216398
    Abstract: A second stage screening system configured to resolve a threat alarm detected in a cargo by a first stage screening system. The second stage screening system includes layers of first muon detectors placed above the cargo to detect a first coordinate and an angle of incidence of incoming muons and layers of second muon detectors placed below the cargo to detect an actual coordinate and an actual angle of exit of the incoming muons. The first and second detectors measure a momentum of the incoming muons. A processing unit receives threat sensitivity vectors determined from the first stage, operates a cargo positioning system that centers a high-Z threat within the cargo, relative to the first and second muon detectors, and analyzes the momentum and a distribution of deflection angles between the angles of incidence and exit to resolve the threat alarm.
