    摘要: An inspection system for scanning cargo and vehicles is described which employs an X-ray source that includes an electron beam generator, for generating an electron beam; an accelerator for accelerating said electron beam in a first direction; and, a first set of magnetic elements for transporting said electron beam into a magnetic field created by a second set of magnetic elements, wherein the magnetic field created by said second set of magnetic elements causes said electron beam to strike a target such that the target substantially only generates X-rays focused toward a high density section in the scanned object, which is estimated in a second pulse using image data captured by a detector array in a first pulse. The electron beam direction is optimized by said X-ray source during said second pulse to focus X-rays towards said high density section based on said image data in said first pulse.

    摘要: Systems and methods for detecting Compton scatter are provided. The system includes a first detector configured to detect incident radiation and output a first detector signal; more than one second detectors surrounding the first detector and configured to detect incident radiation scattered by the first detector, wherein each of the second detectors output a second detector signal, and wherein a signal decay time of the first detector signal differs from the signal decay time of the second detector signals; and a digitizer configured to receive a single input consisting of output signals from each of the first detector and the plurality of second detectors, wherein the digitizer is further configured to simultaneously digitize the signals to produce a digitized output waveform, and wherein a shape of the output waveform is indicative of a presence or an absence of a Compton scatter signal. The systems and methods are also configured to detect pulse pileup, with or without second detectors.
