とを特徴とするＣＴ装置用Ｘ線検出器。 A first photoelectric conversion element that enters the light emitted by the scintillator and converts it into an electrical signal is provided on the rear surface of the X-ray transmission side of the scintillator that emits light when X-rays are incident thereon. A light guide made of a material that absorbs little X-rays and has good light transmittance is provided on the front surface of the scintillator, with one end protruding outward from one side of the scintillator. A light reflective layer is provided on the entire surface, and the light emitted by the scintillator guided through the light guide is incident on the surface opposite to the light reflective layer at one end of the light guide and converted into an electrical signal. An X-ray detector for a CT apparatus, characterized in that a second photoelectric conversion element is provided.
