Abstract: A digital X-ray apparatus forms a latent image of an object on a photostimulable phosphor plate as an energy distribution pattern using X-ray energy and reads the latent image using an excitation light beam. A plate, of a material which does not transmit the excitation light beam, has holes formed therein with photostimulable phosphor positioned in the holes, the photostimulable phosphor emitting a fluorescent light when irradiated by the excitation light beam, the emitted light beam gathered and a corresponding signal produced. The excitation light beam reflected from the photostimulable phosphor plate is also gathered and a signal responsive thereto also is produced. A method of production by stacking and bonding plural metal sheets having appropriate patterns of holes therein with the photostimulable phosphor and a transparent protection film layer thereon provides the structure of the photostimulable phosphor plate.
