Abstract: A method for imaging a target with an x-ray scatter apparatus. Air scatter from air intervening between the x-ray scatter apparatus and a target overwhelms x-ray scatter from the target in that x-ray scatter from a position on the target is no more than 10% of the x-ray scatter due to intervening air scatter that reaches at least one point in the detector plane of the x-ray scatter apparatus. The target is illuminated with a beam of x-rays scanned across the target, and x-rays scattered by the target are detected using a detector with a centroid displaced with respect to the beam axis by at least five feet. The detector signal is then processed to generate an image of the target. The beam of x-rays may be unshielded, and/or the detector may be uncollimated.

Abstract: An x-ray tube for generating a sweeping x-ray beam. A cathode is disposed within a vacuum enclosure and emits a beam of electrons attracted toward a rotating anode. The rotating anode is adapted for rotation with respect to the vacuum enclosure about an axis of rotation. At least one collimator opening or aperture corotates with the rotating anode within the vacuum enclosure, such that a swept x-ray beam is emitted.

Abstract: Methods and apparatus for parcel inspection with x-rays. A source of penetrating radiation contained entirely within an enclosing body of a conveyance generates a beam of penetrating radiation incident upon a parcel while the parcel is disposed externally to the enclosing body. A detector generates an inspection signal based on detection of penetrating radiation after interaction with contents of the parcel. A conveyor positions the parcel with respect to the beam of penetrating radiation, while a processor ascertains a specified characteristic of the parcel based on the inspection signal.

Abstract: An x-ray inspection system using backscatter of an x-ray beam emitted through a scan panel contiguous with, but of a material distinct from, an enclosure that contains an x-ray source by which the x-ray beam is generated. The scan panel is contoured in such a manner as to be visibly blended with a shape characterizing the enclosure. In some embodiments, the beam traverses multiple scan panels, where one or more of the scan panels may be selected for beam filtration properties. The scan panel may be disposed interior to a sliding door, and may be structured to serve as a scatter shield.

Abstract: Apparatus for imaging items behind a concealing barrier. A source of penetrating radiation is contained entirely within a housing. A spatial modulator forms the penetrating radiation into a beam and sweeps the beam to irradiate an inspected object. A detector generates a scatter signal based on penetrating radiation scattered by contents of the inspected object, and a sensor senses motion relative to a previous position of the apparatus with respect to the inspected object. A processor receives the scatter signal and generates an image of the contents of the inspected object based at least on the scatter signal. The housing may be adapted for singled-handed retention by an operator
