Claims (3)
- 受光素子の受光面上にシンチレーション結晶を3次元に配列し、放射線を検出した結晶の応答を2次元位置ヒストグラム上で識別可能とすることで、放射線検出位置を3次元で得るようにしたDOI型放射線検出器において、
前記シンチレーション結晶を正3角柱とし、前記2次元位置ヒストグラム上の各結晶の応答を層毎にずらすと共に、
同層の前記シンチレーション結晶間の一部に反射材を設けることにより、少なくとも一部の層における前記2次元位置ヒストグラム上の各結晶の応答を、該2次元位置ヒストグラム上の各結晶の中心からずらすことを特徴とするDOI型放射線検出器。 - 前記反射材の位置を層毎に変えることを特徴とする請求項1に記載のDOI型放射線検出器。
- 同じ材質の前記シンチレーション結晶で、前記2次元位置ヒストグラム上の各結晶の応答を層毎にずらして積層した1つのセットを構成し、セット毎にシンチレーション結晶の材質を変えた複数のセットを積層して、1つのDOI型放射線検出器を更に多層化することを特徴とする請求項1又は2に記載のDOI型放射線検出器。
