    摘要: An image recording sheet and a solid-state image detector are used. The sheet has a stimulable phosphor layer laminated on a base, and the solid-state image detector includes a photoconductive layer containing amorphous selenium as its main component and electrodes disposed on opposite sides of the photoconductive layer. An electric field is applied across the photoconductive layer so that avalanche amplification is obtained within the photoconductive layer. The sheet is scanned under the electric field with stimulating light of wavelength of about 600 nm, and photostimulated luminescence light of wavelength of about 400 nm emitted from the fluorescent layer is incident on the photoconductive layer via an optical guide and a stimulating light cut filter. Electric charge generated within the photoconductive layer is detected by a current detecting circuit, whereby a radiation image signal is obtained.

    摘要: An image signal is read out 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. Stimulating light is caused to scan a stimulable phosphor sheet which has been exposed to radiation and has stored an image, the photoconductive material layer is caused to be exposed to stimulated emission emitted from the stimulable phosphor sheet upon exposure to the stimulating light. Then electric charges generated in the photoconductive material layer upon exposure to the stimulated emission is detected by applying an electric field to the photoconductive material layer. The 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. The solid image sensor has a photoconductive material layer whose major component is a-Se, and the electric field is such as to generate an avalanche amplification effect in the photoconductive material layer.

    摘要: A radiation image detector with improved readout efficiency. The detector records a radiation image by generating and storing electric charges when irradiated with radiation, and the image is read out by irradiating readout light. The detector includes first line electrodes and second line electrodes disposed alternately with each other. An opaque line insulator that blocks the readout light is provided on each side face extending in the longitudinal direction of each second line electrode. The insulator has a width smaller than the distance between the first and second line electrodes. This arrangement allows the electric charges in the area of the photoconductive layer adjacent to the side faces of the first line electrodes to be fully discharged, and the electric charges in the area of the photoconductive layer adjacent to the side faces of the second line electrodes to be prevented from discharging.
