Abstract
Image storage assemblies comprise thin metal screens adjacent storage phosphor screens. The thin metal screen is from about 0.01 to about 0.75 mm in thickness when composed of copper and from about 0.05 to about 0.4 mm when composed of lead. These image storage assemblies can be used in portal imaging whereby both imaging and stimulating radiation are directed through the thin metal screens before the radiation reaches the storage phosphor screens.
