Abstract:
1. An image read-out method of obtaining an image signal bearing thereon image information by use of a stimulable phosphor sheet having a layer of stimulable phosphor which emits stimulated emission in proportion to the stored energy of radiation upon exposure to stimulating light and a solid image sensor having a photoconductive material layer which exhibits electric conductivity upon exposure to the stimulated emission from the stimulable phosphor sheet and a pair of electrode layers which are disposed on opposite sides of the photoconductive material layer and are provided with electrodes for detecting electric charges generated in the photoconductive material layer, and by scanning with stimulating light a stimulable phosphor sheet which has been exposed to radiation and has stored thereon an image, causing the photoconductive material layer to be exposed to stimulated emission emitted from the stimulable phosphor sheet upon exposure to the stimulating light, and detecting electric charges generated in the photoconductive material layer upon exposure to the stimulated emission by applying an electric field to the photoconductive material layer, said method further comprising administering on the image signal a process which suppresses fluctuation of the image signal due to fluctuation in the electric field applied to the photoconductive material layer, said stimulable phosphor sheet has a layer of stimulable phosphor which is stimulated by stimulating light in a wavelength range of not shorter than 600 nm and emits stimulated emission in a wavelength range of not longer than 500 nm, said solid image sensor has a photoconductive material layer whose major component is a-Se, and the electrode of at least one of the electrode layers is divided by picture element pitches into a stripe electrode comprising a plurality of line electrode elements arranged in a row.
