A radiation image storage panel is composed of a phosphor layer consisting essentially of phosphor in the form of columnar crystals and a protective layer provided on the phosphor layer via an adhesive layer, in which the adhesive layer has a thickness of 0. In one embodiment, a cabinet has a play area between an upwardly extending console and a supporting base portion. The storage devices provide a plurality of virtual storage areas, where each virtual storage area is assigned to a user. Then, the device generates a second improved reverberation component using the first de-reverberated output signal.
