と同時に蛍光イメージングを兼用可能な装置は、生体研究を更に進展させるものとして期待される。我々はこれまで高感度と高解像度を両立するPET 用4 層DOI（Depth of Interaction）検出器を開発してきた。この検出器が近接撮像にも有効であることに着目し、近接撮像が必要である蛍光イメージングとの同時撮像が可能なPET 用検出器の開発を考えた。PET 用検出器のシンチレータの外周は内部で発生したシンチレーション光の漏洩を防ぐために反射材で覆われており（図左）、この反射材が取り除かれた場合、PET 用検出器としての性能は大きく劣化してしまう（図中央）。しかしシンチレータ外部から来る蛍光はこの反射材を透過出来ないため、蛍光イメージングとの兼用検出器を考える場合は反射材を取り除かなければならない。そこで我々はシンチレーション光と蛍光の波長が異なることを利用し、シンチレーション光を反射し蛍光を透過できるダイクロイックミラーをシンチレータの蛍光入射面に用いることで（図右）、反射材を取り除いた場合に比べPET 検出器としての性能を回復させることに成功した。このダイクロイックミラーを用いた場合を、反射材を取り除いた場合、従来通りに反射材を使用した場合と比較しそのPET 検出器としての性能評価を行った。","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地,
