ABSTRACT:
In a radiation image read-out method and apparatus, light emitted by a stimulable phosphor sheet carrying a radiation image stored therein, when it is exposed to stimulating rays, is detected by a photoelectric read-out unit comprising three or more photodetectors positioned side by side in the scanning line direction. From the output of the at least one photodetector, which receives the light emitted by a scanning point, outputs of the other photodetectors, multiplied by a predetermined coefficient, are subtracted. The result of the subtraction is used as a read-out image signal.
