Abstract
Provided is an X-ray image detector in which an organic conductive polymer layer which generates electron-hole pairs in reaction to a radioactive ray is employed as an X-ray receptor. In the X-ray image detector, organic conductive polymer substituting a-Se that is an existing photoconductive substance is used and a fluorescent layer diverging light of a visible ray area that is a polymer absorption wavelength band is combined, to detect an electric signal of a polymer having a photoconductive characteristic.
Claims7
An X-ray image detector comprising:
- an insulation substrate which is a physical support body;
- a first electrode layer which is an electron collecting electrode formed on an upper surface of the substrate;
- an organic conductive polymer layer formed on the upper surface of the first electrode layer and generating electron-hole pairs by a radioactive ray or a visible ray;
- a second electrode layer formed on an upper surface of the organic conductive polymer layer;
- a fluorescent layer disposed on an upper surface of the second electrode layer or a lower surface of the substrate;
- and
- a readout apparatus connected to the first electrode layer on the substrate and detecting an electric image signal generated by the radioactive ray in the organic conductive polymer layer.
