摘要： A cargo inspection system and active inspection methods for operating the same to confirm or clear a presence of explosives and/or nuclear materials in cargo. The active inspection methods use high-energy photons and/or neutrons to induce fission, and measure prompt neutrons, delayed neutrons, and delayed gamma-rays. Additionally, if one or more suspect objects are identified within the cargo with a preceding radiographic or computed tomography scan, a microprocessor calculates a position that produces optimal active inspection signals. The cargo or one of a primary radiation source, a secondary radiation source, or one or more radiation detectors are moved to this calculated position before fission occurs.

摘要： A method of determining a presence of items of interest within a cargo container is disclosed. The method includes obtaining information from an initial radiation scan of at least one of the cargo container and contents therein, identifying a target portion of the cargo container in response to the information obtained, transmitting a target radiation beam along the target portion of the cargo container, and detecting radiation received in response to the transmitting. The method further includes analyzing the detected radiation for a presence of items of interest, and in response to the analyzing, generating a first signal indicative of the presence of the items of interest, or generating a second signal indicative of an absence of the items of interest.

摘要： The present invention provides a gamma-neutron detector based on mixtures of thermal neutron absorbers that produce heavy-particle emission following thermal capture. The detector consists of one or more thin screens embedded in transparent hydrogenous light guides, which also serve as a neutron moderator. The emitted particles interact with the scintillator screen and produce a high light output, which is collected by the light guides into a photomultiplier tube and produces a signal from which the neutrons are counted. Simultaneous gamma-ray detection is provided by replacing the light guide material with a plastic scintillator. The plastic scintillator serves as the gamma-ray detector, moderator and light guide. The neutrons and gamma-ray events are separated employing Pulse-Shape Discrimination (PSD). The detector can be used in several scanning configurations including portal, drive-through, drive-by, handheld and backpack, etc.

摘要： The present invention provides a multi-view X-ray inspection system. In one embodiment, a beam steering mechanism directs the electron beam from an X-ray source to multiple production targets which generate X-rays for scanning which are subsequently detected by a plurality of detectors to produce multiple image slices (views). The system is adapted for use in CT systems. In one embodiment of a CT system, the X-ray source and detectors rotate around the object covering an angle sufficient for reconstructing a CT image and then reverse to rotate around the object in the opposite direction. The inspection system, in any configuration, can be deployed inside a vehicle for use as a mobile detection system.
