ABSTRACT:
In a radiation image read-out method, a radiation image storage panel, on which a radiation image has been stored, is exposed to stimulating rays, which cause the panel to emit light in proportion to the amount of energy stored thereon during its exposure to radiation. The emitted light is photoelectrically detected with a photoelectric read-out device, which has detection characteristics such that it may detect light having wavelengths within a wavelength distribution range different from the wavelength distribution range of the stimulating rays and may not detect light having wavelengths within the wavelength distribution range of the stimulating rays. An image signal representing the radiation image is thereby obtained. An identification code is formed on a portion of the radiation image storage panel by using a fluorescent substance. When the fluorescent substance is exposed to the stimulating rays, it produces the fluorescence having wavelengths capable of being detected by the photoelectric read-out device. The identification code is used such that it may be clear which identification code corresponds to which information providing specific information about a radiation image.
