Abstract: The present invention discloses a stationary real-time CT imaging system, comprising an annular photon counting detector, an annular scanning x-ray source, and a scanning sequence controller. Under the control of the scanning sequence controller, the annular scanning x-ray source emits x-ray, and the x-ray penetrates the object being tested and projects onto the corresponding annular photon counting detector. The annular photon counting detector delivers the corresponding exposure information through the main scanning machine and the main controlling unit to a CT main machine and a human-machine interface unit. The image reconstruction is completed in the CT main machine and the human-machine interface unit. By electronically controlling and switching x-ray projection positions in order, the scanning speed is enhanced by tens of times, thereby obtaining dynamic 3D images.

Abstract: A photon count-based radiation imaging system. The invention also relates to a method of implementing X-ray imaging in said system, and to key apparatus of said system. In the system, an x-ray source directs x-rays at a sample on a scanning platform. When the x-rays pass through said sample, photons carrying information about characteristics of the material at various spatial positions are produced. A photon count detector counts the photons on an imaging plane, obtains incident photon projection data and energy data, and transmits same to a 3D reconstruction system. The 3D reconstruction system reconstructs, on the basis of said projection data and energy data, the 3D structure and the matter composition inside the sample, then performs digital dyeing on the component parts of the sample, thereby differentiating the matter composition of the sample.
