Method of adjusting radiation image read-out conditions.

摘要

In a method of adjusting readout conditions for final read-out of a radiation image stored in a stimulable phosphor sheet by limiting the irradiation field, image information obtained by preliminary read-out is subjected to a threshold value processing to detect a background portion inside of the irradiation field. The image information inside of the irradiation field constituted by the background portion and an object image portion surrounded by the background portion is selected from the image information obtained by the preliminary readout. The read-out conditions in the final readout are adjusted on the basis of the selected image information.
