Mapping and imaging ionizing radiation in two and three dimensions

A two-dimensional imaging system and a two-dimensional or three-dimensional optical tomographic mapping system, each employing gas scintillation induced by ionizing radiation, i.e., radioluminescence, and corresponding methods, are disclosed. The systems may employ one or more cameras and corresponding UV filters (potentially solar blind filters) for imaging a radioluminescent scene. For two-dimensional or three-dimensional mapping, the resultant UV images are spatially registered with one another and then reconstructed to form a three-dimensional tomographic map of the ionizing radiation. The two-dimensional map is a plane of the three-dimensional map. The UV images may be spatially registered by using a reference source, optionally, a calibrated reference source allowing dosimetry calculations for the ionizing radiation. Molecular nitrogen is the primary candidate for the radioluminescent gas, though a controlled ambient in a chamber of nitric oxide, argon, krypton, or xenon may be employed. The reconstruction process employs an algebraic reconstruction technique or an Abel inversion.

INTEGRATION OF INSPECTION SCANNERS TO CARGO CONTAINER PROCESSING SYSTEM FOR EFFICIENT PROCESSING AND SCANNING OF CARGO CONTAINERS AT A PORT

Methods and systems are disclosed for the deployment and operation of shipping container scanning systems that enables scanning of containers passing through a modern, highly automated port without impeding the flow of commerce. Locating the scanners where container dwell time is already longest, and configuring scanners to scan up to several containers in parallel but under separate scanning control, minimizes any delay associated with scanning. Operationally integrating scanning systems with the automated logistical port systems ensures smooth, delay-free operation. Controlling the flow of information so that scanning results, including but not limited to images and assessments of the presence or absence of threat material or contraband, are sent only to government Customs and/or security facilities adjacent to but separate from the port insulates port operators from involvement in activities that could slow container throughput.
