Abstract

　本発明の核医学診断装置は、被検者を間に位置づけて配置され前記被検者から放出される放射線又は光子を反応させ、少なくとも第一の反応の位置情報、及び前記反応によって生じる荷電粒子の運動量の情報をそれぞれ検出する前段検出器と、前記前段検出器により反応した放射線又は光子を検出し得る位置に配置され前記反応によって散乱した放射線又は光子に関する情報を検出する後段検出器と、前記前段検出器及び前記後段検出器によって情報を処理する信号処理手段と、画像を再構成するための画像再構成手段と、を備えた核医学診断装置において、前記被検者から放出された放射線又は光子の発生箇所に係る発生情報をコンプトン散乱の運動学に基づいて前記発生情報を分類する情報分類手段と、前記情報分類手段によって分類された発生情報をその情報に応じて異なる画像再構成を行い得るように前記画像再構成手段に提供する情報提供手段と、を備える。
