Publication number: 20140185756Abstract: 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.Type: ApplicationFiled: March 13, 2014Publication date: July 3, 2014Applicant: L-3 Communications Security and Detection Systems, Inc.Inventor: Andrew Dean Foland

Patent number: 7903781Abstract: A distribution of heavy particle stopping power is be determined. A distribution of effective atomic number of a three-dimensional space is accessed, and a distribution of an x-ray stopping power of the three-dimensional space is accessed. A conversion is applied to the distribution of the effective atomic number and the distribution of x-ray stopping power. A distribution of the heavy particle stopping power of the three-dimensional space is generated based on the conversion, the heavy particle stopping power being an indication of a depth of penetration for a heavy particle incident on the three-dimensional space.Type: GrantFiled: May 1, 2009Date of Patent: March 8, 2011Assignee: L-3 Communications Security and Detection Systems, Inc.Inventors: Andrew Dean Foland, Boris Oreper

Patent number: 7606349Abstract: A system may comprise a cathode, a target, one or more switches, and a conductive element. The cathode may be configured and arranged to generate an electron beam, and the target may be configured and arranged to emit radiation when electrons in the electron beam impact the target after being accelerated by an energy source. The one or more switches may be configured and arranged to apply either a first voltage or a second voltage from a power supply between the cathode and the target. The conductive element may be disposed between the cathode and the target so as to inhibit the electron beam generated by the cathode from reaching the target when a signal is applied to the conductive element.Type: GrantFiled: February 9, 2007Date of Patent: October 20, 2009Assignee: L-3 Communications Security and Detection Systems Inc.Inventors: Boris Oreper, Richard F. Eilbert, Andrew Dean Foland, Kenneth E. Prather, Thomas David Plamondon
