Multi-spectral static CT apparatuses

摘要

Multi-spectral static CT apparatuses are disclosed. The apparatus includes a ray source in a form of multiple distributed spots, multiple columns of detectors, a data acquisition device, a luggage carrying and control device, and a multi-spectral projection data processing device. An object of the present disclosure is to combine static CT scanning technology with multi-spectral analysis technology. It has advantages of the static CT system, such as high scanning speed, simple mechanic structure, cost reduction due to omission of slip ring. It also can perform identification of material in an article, and can be widely applied in occasions like safety inspection, and smuggling suppression at customs.
