Radiation image read-out method and apparatus

摘要

In a radiation image read-out system wherein a stimulable phosphor sheet carrying a radiation image stored therein is exposed to stimulating rays which cause it to emit light in proportion to radiation energy stored therein, and the emitted light is photoelectrically read out, preliminary read-out is conducted to investigate the image input information in the stimulable phosphor sheet by use of stimulating rays having a wavelength different from the wavelength of stimulating rays employed in final read-out.
