Radiation image read-out method and apparatus

摘要

In a radiation image read-out method and apparatus wherein preliminary read-out is conducted prior to final read-out for adjusting final read-out conditions and/or image processing conditions for a radiation image stored in a stimulable phosphor sheet, the light detection range of a light detector for detecting light emitted by the stimulable phosphor sheet upon exposure to stimulating rays in the preliminary read-out is changed in accordance with radiation image recording conditions, so that the emitted light is detected over the whole light emission intensity range fixed by the image recording conditions.
