摘要： A mobile scanning system and methods for inspecting contents of a container. Multiple detector plates are arrayed along an arcuate member coupled to a conveyance with wheels, capable of road travel. A source generates high-energy penetrating radiation that irradiates each of the detector plates from a single position. The arcuate member is disposed, during the course of operation of the system, in a vertical plane. The system has one actuator for rotating the arcuate member about a horizontal pivot into a horizontal plane, and a second actuator for further rotating the arcuate member, once rotated into the horizontal plane, about a vertical pivot, so that the arcuate member is contained, for purposes of transport, entirely within a volume defined by a rectangular prism that does not extend horizontally outward from the conveyance beyond any of its wheels.

摘要： A detector and methods for producing x-ray images, more particularly based on x-rays transmitted through an inspected object. A scintillating region is translated along a path within a cross section of a beam, the cross section taken in a plane distal to the object with respect to a source of the beam. Light emitted by the scintillator region is detected, thereby generating a detection signal, the detection signal is received by a processor which generates an image signal, and an image depicting transmitted penetrating radiation is formed on the basis of the image signal.

摘要： Systems and methods for inspecting an object with a scanned beam of penetrating radiation are disclosed. Scattered radiation from the beam is detected, in either the backward or forward direction. Characteristic values of the backscattered radiation are compared to expected reference values to characterize the object. Additionally, penetrating radiation transmitted through the inspected object may be combined with scatter information. In certain embodiments, the inspected field of view is less than 0.1 steradians, and the detector is separate from the source of penetrating radiation and is disposed, with respect to the object, such as to subtend greater than 0.5 steradians in the field of view of the object.

摘要： A system and method for inspecting an object with multiple sources of penetrating radiation. Irradiation of the inspected object by the sources is temporally sequenced such that the source of detected scattered radiation is unambiguous. Thus, multiple views of the inspected object may be obtained and image quality may be enhanced, even in a compact geometry in which the beams are substantially coplanar.

摘要： A system and methods for non-invasive x-ray inspection of an enclosure in such a manner as to reduce the ambient radiation dose to below a specified level. A beam spectrally filtered to emphasize a high-energy component of penetrating radiation is interleaved, temporally, with a beam dominated by a low-energy component. Thus both lightly loaded and heavily loaded cargo may be inspected while limiting the ambient scattered radiation.

摘要： A method and apparatus for producing a scanned beam of penetrating radiation. A beam of particles illuminates a portion of a target, the illuminated portion comprising a focal spot having a centroid. Illumination of the target creates a beam of penetrating radiation such as x-rays. The beam of particles is swept across the target in such a manner that the centroid of the focal spot lies on a line defined by the instantaneous direction of the beam of penetrating radiation as defined, in turn, by a collimating path.
