  • Patent number: 11397276
    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: 10600609
    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: 20200025955
    Abstract: The present specification discloses methods for inspecting an object. The method includes scanning an object in a two-step process. In the primary scan, a truck or cargo container (container) is completely scanned with a fan beam radiation, the transmitted radiation is measured with an array of detectors, and the transmission information and optionally the fission signatures are analyzed to determine the presence of high-density, high-Z and fissionable materials. If the container alarms in one or more areas, the areas are subjected to a secondary scan. This is done by precisely repositioning the container to the location of the suspect areas, adjusting the scanning system to focus on the suspect areas, performing a stationary irradiation of the areas, and analyzing the measured feature signatures to clear or confirm the presence of SNM.
