  • Patent number: 10119923
    Abstract: Methodologies, systems, apparatus, and non-transitory computer-readable media are described herein to facilitate acquisition of volumetric data and volumetric image reconstruction. An imaging system can be configured to transport an object at a speed relative to the scan path of an X-ray source such that insufficient measurement data is collected for classically complete geometrical coverage. Iterative image reconstruction techniques may be used to generate volumetric images based on measured volumetric data of at least a portion of the object.

  • Publication number: 20170323436
    Abstract: Systems, methods, and non-transitory computer-readable media taught herein process a subset of a three-dimensional array of voxels to form an image of a region of interest in an object. Images thus formed are clear, comprehensible, and contextual.

  • Patent number: 9069092
    Abstract: A system and method for imaging objects with a sparse detector array that includes fewer detectors than conventional x-ray scanning systems. The sparse detector array is positioned to receive x-ray radiation from the at least one x-ray source after passing through an inspection area. The sparse detector array includes a plurality of rows of detector elements, wherein at least some of the plurality of rows are separated by gaps such that the at least some of the plurality of rows are non-contiguous. An iterative reconstruction process is used to determine a volumetric image of the object from the radiation measurements recorded by the detectors in the sparse detector array.

  • Patent number: 8644549
    Abstract: A system and method for forming volumetric images of an imaged object based on multiple radiation measurements of the object taken from different angles. A first volumetric image of the object may be calculated using a direct reconstruction method from a plurality of radiation measurements of the object. At least one iteration of an iterative reconstruction method may be performed to compute a second volumetric image of the object. The iterative reconstruction method may be initialized with the first volumetric image of the object.

  • Patent number: 7831012
    Abstract: An apparatus may comprise a frame supporting at least first and second skewed radiation sources and at least first and second radiation detectors. The first and second radiation detectors may be substantially non-contiguous such that a substantial gap exists between the first and second radiation detectors that is free of any radiation detectors. Each of the first and second radiation detectors may also configured and arranged to detect radiation emitted by each of the first and second skewed radiation sources.

  • Patent number: 7809104
    Abstract: An imaging system that can form an image of an item under inspection using scattered radiation. A pencil beam of radiation is steered over the item under inspection and scattered radiation is detected. Regions of the item under inspection from which radiation is scattered are resolved in three dimensions using two-dimensional coordinates to which the pencil beam is steered. The third dimension is resolved using time of flight from the source. Because the inspection system can be located on one side of an item under inspection, an item may be imaged from a long distance and the imaging system may be mounted on a moving vehicle, making the imaging system well suited for use in many security inspection systems to detect explosives and other contraband items.

  • Patent number: 7606348
    Abstract: A method for operating an inspection system is disclosed in which an item under inspection may be moved between radiation sources and detectors illuminated by the sources. The radiation sources may be positioned such that radiation from at least some of the sources impinge on the radiation detectors, forming acute angles with respect to a plane having a normal direction coinciding with the first direction that are substantially in excess of three degrees. Data accumulated by the radiation detectors may be processed to form a three-dimensional tomographic data image of at least a portion of the item under inspection. The processing may be performed using an algebraic reconstruction technique using an inverse system matrix. The inverse matrix can be derived without first computing a transpose of the system matrix.
