Abstract A storage phosphor cassette assembly includes a rectangular cassette and a photo-stimulable storage phosphor mounted on a rigid plate removably positioned within the cassette. The rectangular cassette is closed on five sides and has a side opening which is closed off by a rib on the end of the storage phosphor plate. The cassette and rib are configured to provide a light lock to prevent undesirable exposure of the storage phosphor.
