Multi-stage security screening system and smart communication system

摘要

A multi-stage screening system for screening a container includes a pre-screening stage including a transmission X-ray device. The pre-screening stage is configured to generate constraint data associated with the contents of the container. The system also includes a screening stage including an X-ray diffraction imaging (XDI) device. The screening stage is configured to generate image data associated with the contents of the container. The system further includes a communication system coupled to the pre-screening stage and the screening stage. The communication system is configured to receive and transmit the constraint data and reconstruct at least one image of the container at least partially as a function of the constraint data and the image data.

1. A multi-stage screening system for screening a container, said multi-stage screening system comprising:
a pre-screening stage comprising a transmission X-ray device, said pre-screening stage configured to generate constraint data associated with the contents of the container; a screening stage comprising an X-ray diffraction imaging (XDI) device, said screening stage configured to generate image data associated with the contents of the container; and a communication system coupled to said pre-screening stage and said screening stage, said communication system configured to receive and transmit said constraint data and reconstruct at least one image of the container at least partially as a function of said constraint data and said image data, wherein said communication system is further configured to iteratively reconstruct the at least one image of the container using: estimated XDI image data at least partially generated from said constraint data; actual image data generated by a scan performed by said screening stage; and calculated differences between said estimated XDI image data and the actual image data.
