Abstract

A radiation image detector including the following in the order listed below: a charge storage layer that generates and stores charges by receiving a recording electromagnetic wave representing a radiation image; a photoconductive layer that generates charges by receiving readout light; and an electrode layer having a plurality of first line electrodes that transmits the readout light and is disposed in parallel at a predetermined distance. Further, a second line electrode having electrical continuity with the photoconductive layer is provided between each of the first electrodes, and an opaque line insulator that blocks the readout light is provided on each second line electrode on the side opposite to the photoconductive layer. The opaque line insulator has such a width that a side faceportion of the opaque line insulator resides between the opposing side face portions of adjacent first and second line electrodes.

Description

technical field [0001] The present invention relates to a radiation image detector which receives radiation representing a radiation image, records the radiation image therein, and outputs a signal proportional to the radiation image recorded therein when scanned with readout light. Background technique [0002] Various types of radiation image detectors have been proposed and put into practical use in medicine and other industrial fields. These detectors generate an electrical charge by receiving radiation transmitted through the object under test and store the charge to record a radiation image of the object under test. [0003] Such a radiation image detector is proposed, for example, in US Patent No. 6,770,901. The detector comprises a layer structure arranged in the following order: a first electrode layer that transmits radiation; a recording photoconductive layer that generates charges by receiving radiation; a charge transport layer that acts as an insulator against...
