ABSTRACT:
An X-ray image sensor comprises a fiber optic faceplate, a phospor screen formed on the X-ray incidence side of the faceplate and an image sensing device connected to the other side of the faceplate. A core material of the faceplate is a radiation shielding glass which comprises a compound of high atomic number element and cerium oxide. The sensor can prevent the X-ray radiation damage of the solid-state image sensing device.
