RADIATION IMAGING DEVICE AND RADIATION IMAGING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a technique for reducing missing of image information in gaps between adjacent imaging substrates.SOLUTION: A radiation imaging device includes: an imaging panel in which a plurality of imaging substrates including photoelectric conversion elements are arranged in a manner to form one imaging surface; and a scintillator part which is arranged at a position of covering the imaging panel and which converts radiation into light with a wavelength at which the photoelectric conversion elements can be detected. The scintillator part has a first scintillator layer and a second scintillator layer diffusing the converted light over a wider range than the first scintillator layer at least at a position of covering portions between the plurality of imaging substrates.
