Title:
RADIATION DETECTOR, RADIOGRAPHIC PHOTOGRAPHY DEVICE, AND PRODUCTION METHOD FOR RADIATION DETECTOR
Document Type and Number:
WIPO Patent Application WO/2019/181640
Kind Code:
A1
Abstract:
A radiation detector that includes a flexible substrate, a plurality of pixels that are provided on the substrate and each include a photoelectric conversion element, a scintillator that is laminated on the substrate, and a flexure suppression member that suppresses flexure of the substrate. When X is the size of the pixels, ZL is the limit deformation of the pixels due to flexure of the substrate, and R is the radius of curvature of flexure of the substrate caused by the weight of the scintillator, the rigidity of the flexure suppression member satisfies R≥X2/2ZL.
