    摘要: A scanning unit for identifying contraband within objects, such as cargo containers and luggage, moving through the unit along a first path comprises at least one source of a beam of radiation movable across a second path that is transverse to the first path and extends partially around the first path. A stationary detector transverse to the first path also extends partially around the first path, positioned to detect radiation transmitted through the object during scanning. In one example, a plurality of movable X-ray sources are supported by a semi-circular rail perpendicular to the first path and the detector, which may be a detector array is also semi-circular and perpendicular to the path. A fan beam may also be used. Radiographic images may be obtained and/or computed tomography (“CT”) images may be reconstructed. The images may be analyzed for contraband. Methods of scanning objects are also disclosed.

    摘要: A scanning unit for inspecting objects comprises in one example a radiation source, a movable platform to support an object, and a detector positioned to receive radiation after interaction of radiation with the object. The platform is movable at least partially within a cavity defined, at least partially, below at least one of the source or the detector. In another scanning unit, a first conveyor conveys an object to a movable platform, and second and third conveyors convey the object from the platform. The second and third conveyors are at different vertical heights. In another scanning unit, images from an energy sensitive detector and a spatial detector are fused. In a method, scanning parameters during CT scanning are changed and images reconstructed before and after the change. In another method, an object is scanned with X-ray beams having first and second energy distributions, generated by the same X-ray source.

    摘要: In one example, a scanning unit for examining contents of a cargo container is disclosed comprising a first path through the scanning unit for transport of a cargo container and one or more sources of respective beams of radiation. At least one of the one or more sources are movable across a second path transverse to the first path. The second path extends partially around the first path. The scanning unit further comprises a detector extending partially around the first path. The detector is positioned to detect radiation interacting with the cargo container during scanning, such as radiation transmitted through the container. The at least one source and the detector are positioned so that the cargo container is transportable along the first path, between the source and the detector. A transport system may be provided to convey the object through the scanning unit, along the first path.
