Abstract: This invention provides an x-ray scanning system for scanning an object (22) in a scanning zone. The system comprises an x-ray linear accelerator (20) arranged to irradiate the object with x- radiation having a peak energy of at least 900keV. The system also comprises a back-scatter detector (26) arranged to detect radiation back-scattered from the object. The radiation beam is cone-shaped or fan-shaped and arranged to irradiate the object over a plurality of regions within a single irradiation event. The back-scatter detector comprises a plurality of detection elements, each detection element being arranged to detect scattered radiation from a predefined part of the scanning zone by use of collimators such as zone plates. A signal processor (40) arranged to calculate scatter intensity across the plurality of detector elements.

Abstract: The invention provides a method and system for scanning an object comprising providing a first detector region having a thickness of at least 2 mm and a second detector region having a thickness of at least 5mm wherein the second detector region is arranged to receive radiation that has passed through the first detector region. The method comprises irradiating the object with radiation having having a peak energy of at least IMeV, and detecting the first profile radiation after it has interacted with or passed through the object in order to provide information relating to the object. Detecting the first profile radiation comprises detecting the first profile radiation at the first detector region, receiving the first profile radiation that has passed through the first detector region at the second detector region, and detecting the first profile radiation at the Second detector region. The scanning method further comprises irradiating the object with radiation having a second energy profile, relatively lower than the first energy profile, and having a peak energy of at least 0.5 MeV, detecting the second profile radiation after it has interacted with or passed through the object in order to provide information relating to the object. Detecting the second profile radiation comprises detecting the second profile radiation at the first detector region, receiving the second profile radiation that has passed through the first detector region at the second detector region, and detecting the second profile radiation at the second detector region.

Abstract: The present application discloses a computed tomography system having non-rotating X-ray sources that are programmed to optimize the source firing pattern. In one embodiment, the CT system is a fast cone-beam CT scanner which uses a fixed ring of multiple sources and fixed rings of detectors in an offset geometry. It should be appreciated that the source firing pattern is effectuated by a controller, which implements methods to determine a source firing pattern that are adapted to geometries where the X-ray sources and detector geometry are offset.

Abstract: The present invention is a shielded anode having an anode with a surface facing an electron beam and a shield configured to encompass the anode surface. The shield has at least one aperture and an internal surface facing the anode surface. The shield internal surface and anode surface are separated by a gap in the range of 1 mm to 10 mm. The shield of the present invention is fabricated from a material, such as graphite, that is substantially transmissive to X-ray photons.
