    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: 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: X-ray inspection of moving cargo based on acquiring multiple image lines at one time or substantially at one time. An X-ray source with multiple-beam electron beam targets creates multiple parallel X-ray fan beams. X-ray inspection systems and methods employ such multiple-beam sources for purposes of inspecting fast moving cargo.

    Abstract: An X-ray tube with an anode assembly and specially designed heat transfer element is described. The anode assembly includes an X-ray producing target and a substantially cylindrical electrode that stops or inhibits electrons that may back-scatter from the target. At least one heat transfer element is positioned proximate the anode assembly and in the region between a conducting enclosure and a non-conducting hollow housing or tube. The heat transfer element is positioned to thermally couple the hot anode assembly to an air-cooled conducting enclosure while maintaining an electric isolation.

    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.
