Both are constructed by sandwiching a photoconductive and an electroluminescent layer between two electrodes and they convert X-ray image patterns into visible images. They are thin, flat, lightweight screens and need only 100 to 200 volts 60 Hz driving voltage. The storage type screen displays its visible image for several hours or until it is electrically erased. The nonstorage type amplifier screen is a direct replacement for existing fluoroscopic screens. It provides 10 to 50 times higher brightness, three times better resolution and higher contrast than the best standard fluoroscopic screen.
