In a scintillator used for radiation detection, such as an X-ray CT scanner, a scintillation crystal body having a unidirectional phase separation structure is provided which has a light guide function for crosstalk prevention without using partitions. The phase separation structure includes a first crystal phase and a second crystal phase having a refractive index larger than that of the first crystal phase and which have a first principal surface and a second principal surface, these principal surfaces being not located on the same plane, the first principal surface and the second principal surface have portions to which the second crystal phase is exposed, and a portion of the second crystal phase exposed to the first principal surface and a portion of the second crystal phase exposed to the second principal surface are connected to each other.
摘要:
A radiation detector including a scintillator structure comprising a first plane and a second plane which are not positioned on the same plane, the scintillator structure having an optical waveguiding property in a direction between the first plane and the second plane; and a two-dimensional light receiving element formed of multiple pixels which are disposed parallel to either one of the first plane and the second plane. The radiation detector includes at least one smoothness-deteriorate region which is positioned in one of the first plane and the second plane of the scintillator structure and has an area of 1/6 or more of a light receiving area of each of the multiple pixels. The region is repaired by an optically transparent material so as to be smoothed.
