Abstract
A radiation image sensor comprises (1) an image sensor 1 having a plurality of light receiving elements arranged one or two dimensionally, (2) scintillator 2 having columnar structure formed on the light-receiving surface of this image sensor 1 to convert radiation into light including wavelengths that can be detected by the image sensor 1, (3) a protective film 3 formed so as to cover and adhere to the columnar structure of the scintillator 2, and (4) a radiation-transmittable reflective plate 4 that has a reflective surface 42 disposed to face the image sensor across the protective film 3.
Claims1
A radiation image sensor comprising:
- an image sensor having a plurality of light receiving elements arranged one or two dimensionally;
- scintillator having columnar structure and formed on the light-receiving surface of said image sensor to convert radiation into light including wavelength bands that can be detected by said image sensor;
- a protective film formed so as to cover and adhere to said columnar structure of the scintillator;
- and
- a radiation-transmittable reflective plate having a reflective surface for the light from the scintillator and disposed to face the light-receiving surface of the image sensor across said protective film.
