Development of a large-area multilayer detector for single-shot dual-energy imaging

We have developed a sandwich-like multilayer detector capable of imaging a large field of view for the purpose of dental computed tomography. Two detectors forming the sandwich detector are based on indirect-conversion flat-panel detector technology. This development employed a relatively thin Gd2O2S:Tb scintillator for the front-detector scintillator and a relatively thick CsI:Tl for the rear one. On the other hand, the same photodiode arrays...
