    摘要: 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.

    摘要: In one aspect, an x-ray scanning device is provided. The x-ray scanning device comprises a target adapted to convert electron-beam (e-beam) energy into x-ray energy, a detector array positioned to detect at least some x-rays emitted from the target, and a conveyer mechanism adapted to convey items to be inspected through an inspection region formed by the target and the detector array, wherein the target and the detector array are rotated out of alignment with each other such that x-rays emitted from the target impinge on diametrically positioned detectors of the detector array without passing through near-side detectors of the detector array.

    摘要: 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.

    摘要: Various novel apparatuses and methods for generating X-rays are disclosed. In some embodiments, for example, an apparatus may be configured and arranged so that, for at least one interception point on a particular portion of a scan path on a surface of a target along which a steering element steers an accelerated electron beam (e-beam), both an angle and its complement between a line corresponding to a direction in which the accelerated e-beam is traveling at the interception point and a line oriented normal to the surface of the target at such interception point are greater than forty five degrees.
