METHOD OF ADJUSTING RADIATION IMAGE READ-OUT CONDITIONS AND/OR IMAGE PROCESSING CONDITIONS

In a radiation image recording and reproducing system wherein preliminary read-out and final read-out are conducted for detecting a radiation image stored in a stimulable phosphor sheet, a characteristic value of the radiation image information of a specific region of the stimulable phosphor sheet is calculated on the basis of the radiation image information of the specific region obtained by the preliminary read-out. Final read-out conditions and/or image processing conditions are adjusted on the basis of the characteristic value, thereby simplifying the algorithm for the adjustment.
