Radiation image detecting device

摘要

A substrate is made of copper having an atomic number of 29. The substrate is formed in the shape of a box without a top, and has a rectangular bottom and sidewalls erected at four sides surrounding the bottom. A scintillator is evaporated onto the bottom. The scintillator includes a non-columnar crystal and a plurality of columnar crystals erected by crystal growth. A photodetector tightly adheres to top surfaces of the sidewalls of the substrate through an O-ring, so as to close the top of the box-shaped substrate. The substrate, the photodetector, and the O-ring seal the scintillator in an air-tight manner.

主权项

1. A radiation image detecting device comprising:
a substrate formed of a material containing any one or two or more elements having an atomic number of 20 to 31 as a main ingredient; a scintillator having a plurality of columnar crystals formed on said substrate by evaporation, for converting incident X-ray into light and emitting said light from a tip end portion of each of said columnar crystals; and a board-shaped photodetector opposed to said tip end portions of said columnar crystals, for detecting said light emitted from said tip end portions, wherein said photodetector includes a glass substrate, wherein said photodetector, said scintillator and said substrate are disposed from an upstream side in an X-ray incident direction, and wherein said X-ray enters said scintillator through said photodetector.
