ABSTRACT:
In a system for scanning a stimulable phosphor sheet carrying a radiation image stored therein with a stimulating ray to read out and reproduce the radiation image on a recording medium, the size of the stimulable phosphor sheet is detected, the scanning line density of the stimulating ray and the reproduction scaling factor are changed according to the sheet size to reproduce an image of approximately equal size and resolution on a recording medium of a fixed size. When the size of the recording medium is 257 mm.times.364 mm and those of the stimulable phosphor sheets are 356 mm.times.432 mm, 356 mm.times.356 mm, 254 mm.times.305 mm, and 203 mm.times.254 mm, the scanning line density is set to 5, 5, 6.7, and 10 pixels per millimeter, respectively, and the reproduction scaling factor is set to 1/2, 1/2, 2/3, and 1/1 respectively.
