Description

technical field [0001] The invention relates to a scintillator-based X-ray imaging device, in particular to a scintillator detection system with high detection efficiency and high imaging quality. Background technique [0002] As we all know, scintillator detectors are widely used in X-ray imaging at present. Such as figure 1 As shown, a traditional scintillator detector is mainly composed of a scintillator 1' and an optical imaging system 2', wherein the optical imaging system 2' includes a light collection component 21' (such as a lens group), a photoelectric conversion device 22' (such as a PMT , CCD, CMOS) and electronic equipment 23', in which the scintillator 1' is an important part of it. The scintillator 1' converts X-rays into visible light, which is collected by the light collection component 21', and then is used by the photoelectric conversion device 22' receives it, converts it into an electrical signal, and finally obtains the sample transmission image throug...

Problems solved by technology

However, this preparation process is relatively complicated, and the experimental results show that although adding photonic crystals to the exit surface or incident surface of the scintillator can increase the light output intensity of the scintillator, it will reduce the imaging resolution of the scintillator, especially Yes, in the case of the same photonic crystal structure, the photonic crystal increases the number of photons on the exit surface of the scintillator more than the incident surface of the scintillator, and has a greater impact on the resolution
