The method includes transmitting a radiation beam toward the cargo container, detecting the transmitted radiation beam via a plurality of area radiation detectors, each area radiation detector comprising an active area defined by a matrix of pixels, thereby defining enhanced radiation data, processing the enhanced radiation data and reconstructing the image data set representative of contents of the cargo container, combining image attributes of the image data set to improve the signal to noise ratio, thereby defining an enhanced image data set, and displaying on a display the enhanced image data set comprising an improved signal to noise ratio. | 12-04-2008 |
| 20090168949 | System and method for inspecting containers for target material - A method for automatically inspecting a container for a target material using a computed tomography (CT) scanning system includes performing an initial radiographic scan of the container. Based at least partially on projection data generated during the initial radiographic scan, at least one location within the container is identified that requires CT inspection. A dual energy CT scan of the at least one identified location within the container is performed based on a single energy algorithm or a dual energy algorithm. The dual energy CT scan includes a low energy scan of the at least one identified location and a high energy scan of the at least one identified location. Based on dual energy scan information generated during the dual energy CT scan, a determination is made to confirm or clear an alarm corresponding to the at least one identified location within the container. | 07-02-2009 |
| 20090232277 | SYSTEM AND METHOD FOR INSPECTION OF ITEMS OF INTEREST IN OBJECTS - An inspection system is provided. The inspection system includes at least one radiation source including single or multiple energies and configured to transmit a radiation beam through an object under inspection. The inspection system further includes an array of detectors configured to receive multiple radiation beams transmitted through the object, wherein the array of detectors are oriented at different angles with respect to the radiation beam and wherein at least one of the radiation source, and the array of detectors or the object is configured to be actuated in a translational direction relative to each other. The inspection system further includes processing circuitry coupled to the array of detectors and configured to generate a three dimensional image of the object. | 09-17-2009 |
| 20090283690 | SYSTEM AND METHODS FOR DETECTING CONCEALED NUCLEAR MATERIAL IN CARGO - A cargo inspection system and active inspection methods for operating the same to confirm or clear a presence of explosives and/or nuclear materials in cargo. The active inspection methods use high-energy photons and/or neutrons to induce fission, and measure prompt neutrons, delayed neutrons, and delayed gamma-rays. Additionally, if one or more suspect objects are identified within the cargo with a preceding radiographic or computed tomography scan, a microprocessor calculates a position that produces optimal active inspection signals. The cargo or one of a primary radiation source, a secondary radiation source, or one or more radiation detectors are moved to this calculated position before fission occurs. | 11-19-2009 |
| 20090323889 | XRD-BASED FALSE ALARM RESOLUTION IN MEGAVOLTAGE COMPUTED TOMOGRAPHY SYSTEMS - System and method for XRD-based false alarm resolution in computed tomography (“CT”) threat detection systems. Following a scan of an object with a megavoltage CT-based threat detection system, a suspicious area in the object is identified. The three dimensional position of the suspicious area is used to determine a ray path for the XRD-based threat detection system that provides minimal X-ray attenuation. The object is then positioned for XRD scanning of the suspicious area along this determined ray path. The XRD-based threat detection system is configured to detect high density metals (“HDMs) as well as shielded Special Nuclear Materials (“SNMs”) based on cubic or non-cubic diffraction profiles. | 12-31-2009 |
| 20100166142 | METHOD FOR DETECTING THE PRESENCE OF HIGH ATOMIC NUMBER ELEMENTS - Disclosed herein is a method for detecting high atomic number elements in an article by using radiation having two different energies.
