|20140098937||Mobile Aircraft Inspection System - A system for scanning aircraft for concealed threats is provided. The system comprises a vehicle and a manipulator arm attached with a scanning head that can be maneuvered in multiple directions to completely scan an aircraft from the outside. The system uses transmission based X-ray detection, backscatter based X-ray detection or a combination thereof, in various embodiments. The system also includes gamma-ray and neutron detectors, for detection of nuclear and radioactive materials.||04-10-2014|
|20140044233||Combined Scatter and Transmission Multi-View Imaging System - The present specification discloses a multi-view X-ray inspection system having, in one of several embodiments, a three-view configuration with three X-ray sources. Each X-ray source rotates and is configured to emit a rotating X-ray pencil beam and at least two detector arrays, where each detector array has multiple non-pixellated detectors such that at least a portion of the non-pixellated detectors are oriented toward both the two X-ray sources.||02-13-2014|
|20140042330||Composite Gamma-Neutron Detection System - The present invention provides a gamma-neutron detector based on mixtures of thermal neutron absorbers that produce heavy-particle emission following thermal capture. In one configuration, B-10 based detector is used in a parallel electrode plate geometry that integrates neutron moderating sheets, such as polyethylene, on the back of the electrode plates to thermalize the neutrons and then detect them with high efficiency. The moderator can also be replaced with plastic scintillator sheets viewed with a large area photomultiplier tube to detect gamma-rays as well. The detector can be used in several scanning configurations including portal, drive-through, drive-by, handheld and backpack, etc.||02-13-2014|
|20130336447||X-ray Tomographic Inspection System for the Identification of Specific Target Items - The present invention provides for an improved scanning process with a stationary X-ray source arranged to generate X-rays from a plurality of X-ray source positions around a scanning region, a first set of detectors arranged to detect X-rays transmitted through the scanning region, and at least one processor arranged to process outputs from the first set of detectors to generate tomographic image data. The X-ray screening system is used in combination with other screening technologies, such as NQR-based screening, X-ray diffraction based screening, X-ray back-scatter based screening, or Trace Detection based screening.||12-19-2013|
|20130336446||Scanning Systems - The invention provides methods, systems and detector arrangements for scanning an object moving in a first direction that includes the steps of irradiating the object with radiation having a peak energy of at least 900 keV, providing a first detector region having a thickness of at least 2 mm and a second detector region having a thickness of at least 5 mm where the second detector region is arranged to receive radiation that has passed through the first detector region, and detecting the radiation after it has interacted with or passed through the object in order to provide information relating to the object.||12-19-2013|
|20130329855||Systems and Methods for Using an Intensity-Modulated X-Ray Source - The present application is directed toward an X-ray scanning system having a plurality of detectors and a controller, where a) the controller is configured to receive and identify a minimum X-ray transmission level detected by at least one detector, b) the controller compares the minimum X-ray transmission level to at least one predetermined threshold transmission level, and c) based on said comparison, the controller generates an adjustment signal. The present application further comprises an X-ray source, where the X-ray source receives an adjustment signal and is configured to adjust an X-ray pulse duration based on the adjustment signal.||12-12-2013|
|20130230139||High-Speed Security Inspection System - The present specification discloses a high speed scanning system for scanning cargo carried by rail. The system uses of a two-dimensional X-ray sensor array with, in one embodiment, a cone-beam X-ray geometry. The pulse rate of X-ray source is modulated based on the speed of the moving cargo to allow a distance travelled by the cargo between X-ray pulses to be equal to the width of the detector, for a single energy source, and to half the width of the detector for a dual energy source. This ensures precise timing between the X-ray exposure and the speed of the passing object, and thus accurate scanning of cargo even at high speeds.||09-05-2013|
|20120230463||DATA COLLECTION, PROCESSING AND STORAGE SYSTEMS FOR X-RAY TOMOGRAPHIC IMAGES - The present specification discloses an X-ray scanning system for scanning an object. The processing system has processors adapted to receive X-ray tomographic image data and extract parameters from the data, where the parameters include constant grey level, texture or statistics. The processing system also includes processors for executing decision trees, where the processors receive the parameters and construct information using the parameters and processors for conducting a database search, where the database search maps the information to a threat level and allocates the object being scanned to a safety category.||09-13-2012|
