Abstract
A radiation detector includes a light guide portion optically connecting a first segment positioned closest to the other side in a predetermined direction with a second segment positioned closest to the other side in the predetermined direction.
Claims10
A radiation detector comprising:
- a first scintillator portion including a plurality of first segments arranged along a predetermined direction, and a first optically discontinuous portion provided between the first segments adjacent to each other;
- a second scintillator portion including a plurality of second segments arranged along the predetermined direction, and a second optically discontinuous portion provided between the second segments adjacent to each other;
- a light detection unit optically connected to a first end surface of the first segment positioned closest to one side in the predetermined direction, and a second end surface of the second segment positioned closest to the one side in the predetermined direction;
- and
- a light guide portion optically connecting the first segment positioned closest to the other side in the predetermined direction with the second segment positioned closest to the other side in the predetermined direction,
- wherein the first segment positioned closest to the other side in the predetermined direction and the second segment positioned closest to the other side in the predetermined direction are optically coupled to each other, and
- the first segments other than the first segment positioned closest to the other side in the predetermined direction and the second segments other than the second segment positioned closest to the other side in the predetermined direction are optically separated from each other.
