  • Patent number: 9635748
    Abstract: The present invention proposes a high speed radiographic system for use with megavolt linear-accelerator pulsed x-ray sources to produce video images of large-area fields. A linear accelerator is positioned above a field of view. X-ray photons are directed through an object of interest traveling and/or colliding within the field of view. A large area scintillator system, either truly continuous or in large continuous adjacent pieces, converts the x-ray photons that pass through the object into visible light, and an arrangement of cameras, focused at that plane, where each camera sees a sub-area of the entire scintillator, and these sub-areas overlap somewhat to cover the entire scintillator. The resulting images generated in each camera are synchronized to produce one contiguous, synchronized stream of images.

  • Patent number: 8615067
    Abstract: A method and apparatus for identifying hazardous material or potential dangers. The method and apparatus is directed to a non-destructive, non-intrusive scanning system that uses a dual energy x-ray scanning apparatus to transmit and display data within a computer system. The software within the computer system provides for scan data transfer, a cataloging of image data and real time analytics. The real time analytics will find data from a watch list and correlate the data to the scan; it will also compare the scan data to a reference library, and it will additionally perform advanced pattern correlations to look for unusual and or suspicious patterns.
