Abstract
A new method of photoelectrically reading out a radiation image of one or more spots which is stored and recorded on a stimulable phosphor sheet, to determine position of the spot on the phosphor sheet, comprises the steps of: scanning the stimulable phosphor sheet under rotation twice with stimulating rays giving a linear irradiation area on a surface of the phosphor sheet to form in total an irradiated area in the form of a ring; detecting stimulated emissions caused by a series of the irradiations of stimulating rays separately for each scanning, for obtaining information as to whether the spot is present or absent on the irradiated linear area; and locating the position of the spot on the phosphor sheet by combining the information of the spot obtained in the twice scanning.
