Embodiment Construction

[0016] The presently described scheme advantageously fuses data from multiple sensors such as CT, energy discriminative X-ray detection, and X-ray diffraction (XRD) imaging in order to meet expected detection and false alarm specifications. The energy discrimination or generation of energy-sensitive information in the CT system concept is denoted "spectral CT"; this term has been used to denote the combination of the two concepts. Furthermore, the system topology represents a complete platform migration from rotational and translational techniques to a fully fixed design, which represents a paradigm shift that allows the screener to meet future requirements.

[0017] As described herein, distributed X-ray source technology incorporated in a novel, rotation-free system configuration provides dramatic improvements in image quality across the entire imaging field of view. This also provides uniform threat detectability throughout the imaging volume. Furthermore, the demonstrated...

Abstract

An integrated, multi-sensor, Level 1 screening device is described, which system provides a next-generation Explosives Detection System (EDS) that enables high throughput, while drastically reducing false alarms. In exemplary embodiments, the present system comprises a non-rotational, Computed Tomography (CT) system and a non-translational, X-ray diffraction (XRD) system, both in an inline configuration.

Description

technical field [0001] In general, the present disclosure relates to screening devices for explosive detection, and more particularly, to an integrated multi-sensor screening device for explosive detection that provides high throughput while achieving low false alarm rates. Background technique [0002] Conventional systems provide alternating levels of screening capabilities via different screening devices. For example, a CT system would be used as an initial or level 1 screening device. If a threat is detected and the suspicion cannot be clarified through on-screen review, the bag can go to a secondary or level 2 screening device, which can be an X-ray diffraction system. If the alarm cannot be dismissed, it may be necessary to open the bag for manual inspection of the item causing the alarm, and / or use trace detection techniques to clear the package of suspicion. Each further level of screening requires an additional level of manual manipulation and effort in the techni...
