The photons strike scintillator crystals housed in a tool that encircles the affected person. Crystals Utilized in fashionable imaging equipment differ by manufacturer, Each and every with its personal photon detection generate and determination; a typical crystal variety useful for PET is lutetium oxyorthosilicate.
