Abstract: A system for producing a controllable beam of radiation is controllable electronically, and includes no parts that must move relative to one another while in operation to form the beam. The direction and cross-section of the beam may be controlled electronically by controlling an electron beam. Various embodiments provide an X-ray collimator that allows forming a scanning X-ray beam of desired size and flux independently of the aperture material thickness without requiring movement of the aperture or physical components that create the aperture. Some embodiments provide an X-ray collimator that allows forming a scanning X-ray beam of desired size and flux independently of the beam angle.

Abstract: Methods and an x-ray system for dynamically regulating x-ray dose. An x-ray beam is generated and collimated at a source collimator and detected after the x-ray beam traverses an inspected object. A filter may be dynamically interposed by translation of the filter between a focal spot of the source and the source collimator in such a manner as to maintain the portion of the x-ray beam that traverses the inspected object below a specified limit. Alternatively, an aperture of the source collimator may be varied in size or position relative to the focal spot.

Abstract: Systems and methods for inspecting an object with a scanned beam of penetrating radiation. Scattered radiation from the beam is detected, in either a backward or forward direction, as is radiation transmitted through the inspected object. The source of penetrating radiation is concealed within an enclosure of a road-worthy vehicle, and detected with a large-area uncollimated detector similarly concealed within the enclosure.

Abstract: An apparatus for generating a scanned beam of penetrating electromagnetic radiation. An electron beam is incident on a succession of specific locations on a concave anode which emits electromagnetic waves in response thereto, in such a way that electromagnetic waves exiting from an aperture scan over a range of angles within a scan plane in response to angular scanning of the electron beam. The x-ray beam is extracted from the apparatus via one or more exit apertures in the back hemisphere, on the side of the anode onto which the electron beam impinges.

Abstract: A detector and methods for inspecting material on the basis of scintillator coupled by wavelength-shifting optical fiber to one or more photo-detectors, with a temporal integration of the photo-detector signal. An unpixelated volume of scintillation medium converts energy of incident penetrating radiation into scintillation light which is extracted from a scintillation light extraction region by a plurality of optical waveguides. This geometry provides for efficient and compact detectors, enabling hitherto unattainable geometries for backscatter detection and for energy discrimination of incident radiation. Additional energy-resolving transmission configurations are enabled as are skew- and misalignment compensation.

Abstract: A system and method for inspecting a vehicle by means of one or more sources and detectors of penetrating radiation. The source(s) and detector(s) are carried on a mobile conveyance and deployed at a point of operation. One source swings away from the conveyance on a deployable member, such as a boom, such that the source can irradiate a vehicle from above or below. A detector deploys outwardly from the mobile conveyance, remaining mechanically coupled to the mobile conveyance in a position in a horizontal plane, such that the detector intercepts penetrating radiation from the source positioned above the inspected vehicle, which penetrating radiation has interacted with the inspected vehicle. A ramp may be provided to allow the inspected vehicle to be driven to a position between the vertically irradiating source and a transmission detector.
