Abstract: Methods for generating a multiple-energy X-ray pulse. A beam of electrons is generated with an electron gun and modulated prior to injection into an accelerating structure to achieve at least a first and specified beam current amplitude over the course of respective beam current temporal profiles. A radio frequency field is applied to the accelerating structure with a specified RF field amplitude and a specified RF temporal profile. The first and second specified beam current amplitudes are injected serially, each after a specified delay, in such a manner as to achieve at least two distinct endpoint energies of electrons accelerated within the accelerating structure during a course of a single RF-pulse. The beam of electrons is accelerated by the radio frequency field within the accelerating structure to produce accelerated electrons which impinge upon a target for generating Bremsstrahlung X-rays.

Abstract: Methods for maintaining a specified beam profile of an x-ray beam extracted from an x-ray target over a large range of extraction angles relative to the target. A beam of electrons is generated and directed toward a target at an angle of incidence with respect to the target, with the beam of electrons forming a focal spot corresponding to the cross-section of the electron beam. At least one of a size, shape, and orientation of the electron beam cross-section is dynamically varied as the extraction angle is varied, and the extracted x-ray beam is collimated. Dynamically varying the size, shape or orientation of the electron beam cross-section may be performed using focusing and stigmator coils.

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: 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: A versatile beam scanner for generating a far-field scanned pencil beam, and, alternatively, a far-field pencil beam. An angle selector limits the angular extent of an inner fan beam emitted by a source of penetrating radiation. The source and angle selector may be translated, along a direction parallel to a central axis of a multi-aperture unit, in such a manner as to generate a scanned far-field pencil beam, when rings of apertures are interposed between the source and an inspected target, or, alternatively, a far-field fan beam, when no ring of apertures is interposed.

Abstract: A device for inspecting a cargo container such as a motor vehicle or freight pallet, with penetrating radiation. A source of penetrating radiation is mounted on a moveable bed, thereby allowing a beam of penetrating radiation to sweep the large container. At least one detector is also mounted on the bed, either on the side of the source or on a boom, so that, as the beam is scanned across the container, the container and any contents of the container are characterized by transmitted or scattered radiation, or both.

Abstract: Systems and methods for determining a mass of a crop by using at least one X-ray scanner is provided. The method includes obtaining at least two scan images of the crop, where a first of the at least two images is obtained along a first plane relative to the crop and a second of the at least two images is obtained along a second plane relative to the crop, and where the first plane is angularly displaced relative to the second plane, registering the first image and the second image, correcting the registered first and second images, and determining the mass of the crop from the corrected first and second images.
