The photons strike scintillator crystals housed in a tool that encircles the individual. Crystals used in fashionable imaging devices differ by manufacturer, each with its have photon detection produce and resolution; a typical crystal kind useful for PET is lutetium oxyorthosilicate. The crystals transmit the photoelectric Strength into circuits that transform the electric Electrical power into Laptop data.
