摘要： 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 form 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.
摘要翻译：可以使用散射辐射形成检查中的物品的图像的成像系统。将铅笔的辐射光束转过检查的物品，并检测散射辐射。被辐射散射的被检查物品的区域使用二维坐标进行三维解析，该二维坐标被引导到该笔线束。使用从源头飞行的时间来解决第三个维度。因为检查系统可以位于被检查物品的一侧，所以物品可以从远距离成像，并且成像系统可以安装在移动的车辆上，使得成像系统非常适合用于许多安全检查系统检测炸药等违禁物品。

摘要： A system may comprise a cathode, a target, one or more switches, and a conductive element. The cathode may be configured and arranged to generate an electron beam, and the target may be configured and arranged to emit radiation when electrons in the electron beam impact the target after being accelerated by an energy source. The one or more switches may be configured and arranged to apply either a first voltage or a second voltage from a power supply between the cathode and the target. The conductive element may be disposed between the cathode and the target so as to inhibit the electron beam generated by the cathode from reaching the target when a signal is applied to the conductive element.

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： A method for operating an inspection system is disclosed in which an item under inspection may be moved in a first direction relative to and at least partially between at least one radiation source and at least some radiation detectors illuminated by the at least one radiation source. The radiation source and detectors may be operated such that ray paths extending linearly between the at least one radiation source and at least some of the radiation detectors form 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. In some embodiments, transmission data based upon outputs of a plurality of radiation detectors may be processed to form a tomographic image, in which, for all possible orientations of a three dimensional plane, the orientation vectors of at least some of the rays of radiation for which transmission data was accumulated and used to form the tomographic image form an angle of less than eighty-five degrees or greater than ninety five degrees with respect to the plane.
摘要翻译：公开了一种用于操作检查系统的方法，其中待检查的物品可以相对于并且至少部分地在至少一个辐射源与由至少一个辐射源照射的至少一些辐射探测器之间的第一方向上移动。可以操作辐射源和检测器，使得在至少一个辐射源与至少一些辐射探测器之间线性延伸的射线路径相对于具有与第一方向重合的平面的平面形成锐角，该平面基本上在超过三度。可以处理由辐射检测器累积的数据，以形成被检查物品的至少一部分的三维断层数据图像。在一些实施例中，可以处理基于多个辐射检测器的输出的传输数据以形成断层图像，其中对于三维平面的所有可能的取向，至少一些辐射射线的取向向量用于该传输数据被累积并用于形成相对于该平面小于八十五度或大于九十五度的角度的断层图像。
