    Abstract: This disclosure relates to systems and methods for material discrimination. The systems and methods include a single source that generates both neutrons and photons, and a single imaging array with a common detector that detects the neutrons and the photons generated from the single source. The systems and methods allow for a determination of the contents, and/or the effective atomic number (“Z”) of the contents, of an object without physical inspection of the interior of the object.

    Abstract: An apparatus includes an extendable wand, and a sensor head coupled to the wand. The sensor head includes a continuous wave metal detector (CWMD) and a radar. When the wand is collapsed, the wand and the sensor head collapse to fill a volume that is smaller than a volume filled by the sensor head and the wand when the wand is extended. Frequency-domain data from a sensor configured to sense a region is accessed, the frequency-domain data is transformed to generate a time-domain representation of the region, a first model is determined based on the accessed frequency-domain data, a second model is determined based on the generated time-domain representation, the second model being associated with a particular region within the sensed region, and a background model that represents a background of the region is determined based on the first model and the second model.

    Abstract: Radiation is directed at an object, and radiation scattered by the object is sensed. An angular distribution of scatter in the sensed scattered radiation relative to a path of the radiation directed at the object is determined, and the angular distribution is evaluated. One or more atomic numbers, or effective atomic numbers, of materials composing the object is determined based on evaluating the angular distribution.

    Abstract: A volumetric image of a space is acquired from an imaging system. The space includes an object of interest and another object, and the volumetric image includes data representing the object of interest and the other object. A two-dimensional radiograph of the space is acquired from the imaging system. The two-dimensional radiograph of the space includes data representing the object of interest and the other object. The two-dimensional radiograph and the volumetric image are compared at the imaging system. A two-dimensional image is generated based on the comparison. The generated two-dimensional image includes the object of interest and excludes the other object.

    Abstract: The application discloses a system and methods for remote access and analysis of data collected about items under inspection. The system includes one or more data collection stations, each of which may include an X-ray scanner that scans the items under inspection to obtain data about the items. The data is transmitted to one or more remote stations, where the data is remotely analyzed to determine whether the item contains a potential threat, such as, for example, explosives or other contraband. Data may be aggregated so that correlations between data collected for different items may be used to more accurately detect threats.
