Abstract

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, an article 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 an advantage of a static CT system, such as high scanning speed, simple mechanic structure, and/or 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 such as safety inspection, and smuggling suppression at customs.
