Summary:This invention is directed to radiography and in particular to image storage assemblies that are useful for oncology portal imaging. It also relates to radiation image recording and reproducing method. Thus, this invention is useful in portal radiography. 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.
