OSTI ID:5865200
In a system for reading out radiation image information recorded on a stimulable phosphor sheet which emits light upon stimulation by stimulating rays according to the recorded radiation image information, the phosphor sheet is two-dimensionally scanned by a laser beam and the light emitted therefrom is detected by a photodetector. The integrated output of the photodetector is read out for every unit of time period corresponding to a picture element of the radiation image. Position reference pulses are generated every time the relative position of the laser beam scans on the phosphor sheet by a standard amount in the main scanning direction. The integrated value of the output of the photodetector is read out every time the output is integrated for a fixed time period within each time interval between the position reference pulses.
