X-ray detector and radiographic X-ray apparatus

Abstract

An X-ray detector includes a plurality of scintillators each configured to convert incident X-rays into light and emit the light, a plurality of low refractive layers that are alternately stacked with the plurality of scintillators and that have a refractive index lower than the scintillators, and a photoelectric conversion element array including a plurality of arrayed photoelectric conversion elements each configured to convert the light emitted from the alternately stacked scintillators and low refractive layers into an electrical signal. At least one of the scintillator and the low refractive layer includes a light collecting portion that focuses the emitted light toward a corresponding one of the photoelectric conversion elements.
