Abstract:
A radiation image readout method comprising the steps of:scanning an excitation light in a main scanning direction and a sub scanning direction over the surface of a stimulable phosphor sheet, on which radiation energy has been cumulatively stored, so as to two-dimensionally irradiate the stimulable phosphor sheet with the excitation light, performing readout of the stimulable phosphor sheet by receiving and photoelectrically converting the stimulated emission emitted from the portions of the stimulable phosphor sheet irradiated by the excitation light to obtain an output signal, wherein, when the readout of a plurality of stimulable phosphor sheets having different diffusion rates with respect to the excitation light is to be performed by a single apparatus, the readout is performed by emitting an excitation light of an energy level which is greater as the excitation light diffusion rate of the stimulable phosphor sheet to be read out is smaller.
