Method of adjusting radiation image read-out conditions.

摘要

In a method of adjusting read-out conditions for a radiatipn image stored on a stimulable phosphor sheet by limiting the radiating exposure field, digital image signals at respective positions on the stimulable phosphor sheet are detected on the basis of image information obtained by preliminary read-out. The digital image signals are subjected to a differentiation processing, and the radiation exposure field on the stimulable phosphor sheet is detected by use of the differentiated values obtained thereby. The read-out conditions in final read-out are adjusted on the basis of the image information obtained within the detected radiation exposure field by the preliminary read-out.
