RADIATION DETECTION APPARATUS AND RADIATION DETECTION SYSTEM

摘要

A radiation detection apparatus includes a sensor panel which includes a photoelectric conversion unit, a scintillator layer disposed above the photoelectric conversion unit and configured to convert radiation into light, a reflection layer disposed above the scintillator layer and configured to reflect part of light generated by the scintillator layer toward the sensor panel; and a protective layer which covers the scintillator layer from above the reflection layer. The scintillator layer is fixed on the sensor panel. The reflection layer is fixed on the protective layer. Part of the protective layer is bonded to the sensor panel with an adhesive material so as to seal the scintillator layer and the reflection layer with the protective layer and the sensor panel. An upper surface of the scintillator layer includes a portion which is not fixed to the reflection layer.

1. A radiation detection apparatus comprising:
a sensor panel which includes a photoelectric conversion unit configured to convert light into charge; a scintillator layer disposed above the photoelectric conversion unit of said sensor panel and configured to convert radiation into light having a wavelength convertible by the photoelectric conversion unit; a reflection layer disposed above said scintillator layer and configured to reflect part of light generated by said scintillator layer toward said sensor panel; and a protective layer which covers said scintillator layer from above said reflection layer, wherein said scintillator layer is fixed on said sensor panel, said reflection layer is fixed on said protective layer, part of said protective layer is bonded to said sensor panel with an adhesive material so as to seal said scintillator layer and said reflection layer with said protective layer and said sensor panel, and an upper surface of said scintillator layer includes a portion which is not fixed to said reflection layer.
