  • Patent number: 8180138
    Abstract: A method and system for reconstructing and segmenting an image of the contents of a container. The method includes receiving actual scan data from a scan of the container, reconstructing the actual scan data to obtain a reconstructed image, and segmenting the reconstructed image to obtain a segmented image. The method also includes deriving simulated scan data corresponding to the segmented image, calculating an error term based on a difference between the simulated scan data and the actual scan data, and determining whether a criterion is satisfied. The method further includes using the error term to produce a modified reconstructed image and repeating the preceding steps with the modified reconstructed image substituted for the reconstructed image if the criterion is not satisfied, and outputting information from the segmented image if the criterion is satisfied.

  • Patent number: 8103672
    Abstract: An apparatus, system, and method are disclosed for determining a partial class membership of a data record in a class. The apparatus includes a record set acquisition module that receives a set of reference records having the same independent variables and belonging to a known class within a group of classes. An unknown-class record receiving module receives an unknown-class record having same independent variables as reference records. A class identification module creates a class vector for each reference record identifying whether the record is in a class. A weighting module calculates a set of unknown-class record weights for the unknown-class record. A classification module determines a partial class membership for the unknown-class record for each class in the group of classes using the set of unknown-class record weights. Each partial class membership identifies a probability that the unknown-class record belongs to a corresponding class in the group of classes.

  • 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.
