Abstract
A photo-stimulable phosphor imaging plate having a non-toxic radio-opaque symbol, pattern or indicia formed on one surface, the so called rear surface, which would become visually apparent in an image if the imaging plate was exposed from the wrong side, thereby eliminating confusion that the image is from the opposing side of the face, and a light-opaque, color contrasting, asymmetric symbol or indicia on the front surface eliminating the confusion of a flipped image, and a correspondingly back to back located color contrasting identical asymmetric symbol on the opposite rear surface of the plate, emulating the raised orientation dot of standard intraoral films.
