Patent

CA 2710655

The present invention is directed towards an X-ray people screening system capable of rapidly screening people for detection of metals, low Z materials (plastics, ceramics and illicit drugs) and other contraband which might be concealed beneath the person's clothing or on the person's body. In an exemplary embodiment, the scanning system has two scanning modules that are placed in parallel, yet opposing positions relative to each other. The two modules are spaced to allow a subject, such as a person, to stand and pass between the two scanning modules. The first module and second module each include a radiation source (such as X-ray radiation) and a detector array. The subject under inspection stands between the two modules such that a front side of the subject faces one module and the back side of the subject faces the other module.

La présente invention concerne un système de criblage de personnes par rayons X capable de cribler rapidement des personnes pour la détection de métaux, de matériaux à Z faible (plastiques, céramiques et drogues illicites) et autres contrebandes pouvant être cachées sous les vêtements d'une personne ou sur le corps d'une personne. Selon un exemple de mode de réalisation, le système de balayage comprend deux modules de balayage qui sont placés en parallèle, mais en positions opposées l'un par rapport à l'autre. Les deux modules sont espacés pour permettre à un sujet, par exemple une personne, de se tenir et de passer entre les deux modules de balayage. Le premier module et le second module comprennent chacun une source de rayonnements (par exemple de rayons X) et un réseau de détection. Le sujet inspecté se tient entre les deux modules de manière à ce que l'avant du sujet soit en face d'un module et l'arrière du sujet en face de l'autre module.
