摘要
In a radiation image acquisition apparatus that obtains a radiation image recorded on a stimulable phosphor layer having a plurality of arranged cells, the quantity of stimulated emissions from the stimulable phosphor within each cell is obtained precisely for each cell as a digital image signal. A radiation image conversion panel comprising a phosphor layer formed of multiple cells filled with stimulable phosphor having recorded on the surface thereof a radiation image is scanned with a stimulating light beam by a scanning unit, and the stimulated emissions caused thereby are photoelectrically detected as an analog image signal by a photoelectrical amplifier. The signal component representing the partition walls is recognized, and the component of the analog image signal obtained between the recognized signal components representing the cell partition walls is digitized and a digital image signal is obtained.
