  • Publication number: 20190137651
    Abstract: An X-ray inspection system for scanning objects is provided. The system includes a stationary X-ray source made of one or more linear modules positioned around a scanning volume, and defining sparsely positioned multiple stationary X-ray source points from which X-rays can be directed through the scanning volume. An X-ray detector array extends around the scanning volume and is arranged to detect X-rays from the source points which have passed through the scanning volume. A conveyor is arranged to convey the objects through the scanning volume and at least one processor processes the detected X-rays to produce three dimensional images of the items.

  • Publication number: 20190043686
    Abstract: The present specification discloses a high power continuous X-ray source having a rotating target assembly that is cooled by circulation of a liquid material in contact with the target assembly, whereby the target assembly has a front surface being impinged by electrons and a mechanism for rotating the target assembly. The cooling liquid is always in contact with at least one surface of the target for dissipating the heat generated by the energy deposited by the stream of electrons, thereby lowering the temperature of the target to allow for continuous operation.

  • Publication number: 20180017702
    Abstract: Systems and methods are used to increase the penetration and reduce the exclusion zone of radiographic systems. An X-ray detection method irradiates an object with X-ray fanlets including vertically moving fan beams, each fanlet having an angular range smaller than the angular coverage of the object. The fanlets are produced by modulating an X-ray beam, synchronizing the X-ray beam and the fanlets, detecting the fanlets irradiating the object, collecting image slices from the detector array corresponding to a complete scan cycle of the fanlets, and processing the image slices collected for combining into a composite image.

  • Patent number: 9625606
    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.

  • Patent number: 9557427
    Abstract: The present specification describes systems and methods for the simultaneous detection of radioactive materials such as neutrons, muons and gamma rays based on thin gap chamber technology. A thin-gap chamber (TGC) is disclosed having a thermal neutron absorber material, such as 10B4C or 10B8C, which interacts with neutrons to emit heavy particles. The heavy particles, in turn, interact with the gas present in chamber to produce ionization that is converted into a measurable signal. The TGC is embedded in a neutron moderating medium. The detector systems are fabricated from commercially available construction materials and are easy to manufacture at a reasonable cost when compared to conventional He-3 neutron detector systems.

  • Patent number: 9442213
    Abstract: The present invention provides a multi-view X-ray inspection system. In one embodiment, a beam steering mechanism directs the electron beam from an X-ray source to multiple production targets which generate X-rays for scanning which are subsequently detected by a plurality of detectors to produce multiple image slices (views). The system is adapted for use in CT systems. In one embodiment of a CT system, an electron beam generated by a single radiation source is steered by an electron beam transport mechanism comprising at least two dipoles and a quadrupole on to a target arranged in an approximated arc. The inspection system, in any configuration, can be deployed inside a vehicle for use as a mobile detection system.

  • Patent number: 9435752
    Abstract: The present application discloses scanner systems that have a radiation generator arranged to generate radiation to irradiate an object, a detector arranged to detect the radiation after it has interacted with the object and generate a sequence of detector data sets as the object is moved relative to the generator, and processors arranged to process each of the detector data sets thereby to generate a control output.

  • Publication number: 20160223706
    Abstract: The present specification discloses methods for inspecting liquids, aerosols and gels (LAGs) for threats. The method includes scanning LAGs packed in plastic bags in a multiple step process. In a primary scan, the bag is scanned using dual energy CT technique with fan beam radiation. In case of an alarm, the alarming LAG container is scanned again using coherent X-ray scatter technique with cone beam radiation. The system has a mechanism to switch between two collimators to produce either fan beam or cone beam. The system also has a mechanism to position the target properly for scanning and prevent container overlap when scanning multiple LAG containers in a bag.

  • Patent number: 9329285
    Abstract: The present invention provides a gamma-neutron detector based on mixtures of thermal neutron absorbers that produce heavy-particle emission following thermal capture. In one configuration, B-10 based detector is used in a parallel electrode plate geometry that integrates neutron moderating sheets, such as polyethylene, on the back of the electrode plates to thermalize the neutrons and then detect them with high efficiency. The moderator can also be replaced with plastic scintillator sheets viewed with a large area photomultiplier tube to detect gamma-rays as well. The detector can be used in several scanning configurations including portal, drive-through, drive-by, handheld and backpack, etc.
