Abstract
Abstract A cassette for a photo-stimulable storage phosphor plate has a visual feedback feature for indicating whether the cassette is upside down or right side up. The cassette preferably has a cavity bounded by upper and lower walls, closed side walls a closed end wall and an open end wall. A storage phosphor plate is supported in the cavity and includes a raised rib which closes off the open end wall. A visual feedback feature is located on a closed side or end wall. The feature may include a horizontally corrugated edge texture with different color on the top versus the bottom corrugations. An alternate visual feedback feature may include an adhesive strip of grating or lenticular material showing different colors or differnet visual indicia or messages when viewed from the top and from the bottom.
