  • Publication number: 20180120240
    Abstract: An apparatus having a submersible, hollow, closed container and an x-ray imaging system radiation source disposed within that container. The submersible container is configured to withstand at least 10 atmospheric pressure (atm) and hence to withstand being submerged at least 100 meters (m) in a liquid (such as an open body of water) without undergoing permanent deformation. The x-ray imaging system radiation source intern is configured to selectively direct x-rays towards an object under inspection that is external to the submersible container. Detector components can be similarly placed within the aforementioned container or within one or more additional such containers.

  • Patent number: 9778391
    Abstract: Radiation scanning systems providing multiple views of an object in different planes and a reconstruction algorithm for reconstructing quasi-three-dimensional images from a limited number of views. A system may include bend magnets to direct accelerated charged particles to multiple targets in different viewing locations. Another system collimates radiation generated by a plurality of radiation sources into multiple beams for scanning an object at multiple angles. The object may be a cargo container, for example. The reconstruction algorithm uses an optimization algorithm and imaging and feasibility models to reconstruct quasi-three-dimensional images from the limited number of views.
