Abstract
Image storage assemblies comprise thin metal screens adjacent phosphor storage 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 imaging radiation is directed through the thin metal screens before the phosphor storage screens. Stimulating radiation can then be directed to the phosphor storage screen before it reaches the thin metal screen.
