  • Patent number: 10215879
    Abstract: A computer-implemented method of handling a container includes performing a first scan of the container. The container includes objects therein. The scan includes irradiating the container with polychromatic x-rays with a first x-ray scanning system at a first geographic location and generating a first scan record using a processing device. The method also includes moving the container from the first geographic location to a second geographic location. The method further includes performing a second scan of the container including irradiating the container with polychromatic x-rays with a second x-ray scanning system at the second geographic location and generating a second scan record using a processing device. The method also includes comparing the first scan record and the second scan record. The method further includes determining the second scan record is substantially indistinguishable or distinguishable from the first scan record.

  • Patent number: 9405990
    Abstract: A method of performing a security inspection of a container including a plurality of objects includes irradiating the container with polychromatic x-rays, reconstructing a 4-D voxelized representation defining a momentum transfer spectrum, and generating a 3-D image by determining a single value at each voxel as a function of the momentum transfer spectrum. The method further includes segmenting the voxels into segments of contiguous voxels that map onto at least one object. The method also includes computing an aggregated momentum transfer spectrum over at least a portion of the contiguous voxels through at least one of aggregating the spectra of the contiguous voxels for each segment and defining a supervoxel that includes voxels with the object exclusively and voxels in a neighborhood, regardless of association with the object. The method further includes classifying the object as one of a threat and a non-threat based on the aggregated momentum transfer spectrum.

  • Patent number: 8094783
    Abstract: A method for performing materials analysis of an object using an X-ray system includes generating an X-ray beam using an X-ray source having an anode and acquiring a scatter spectrum from Compton scatter produced when the X-ray beam interacts with the object. The scatter spectrum is acquired using an energy resolving detector. A Compton profile is extracted from the scatter spectrum by processing the scatter spectrum using a control system of the X-ray system. The Compton profile includes peaks at characteristic lines of the anode. The method further includes identifying a characteristic of a material of the object using the Compton profile, and outputting an indication of the characteristic of the material.
