Research Abstract

体内の微小な癌組織が抗原抗体反応などで取り込むアイソトープを利用し、ポジトロンエミッターからのガンマ線を体外から検出することで、動体追跡放射線治療を金マーカーなしで行う方法を検討してきた。これまで行ってきた簡易計算プログラムによる概念設計の結果、18F-FDGを利用した場合、SUV=5であれば直径5cmの腫瘍(放射能:18.5kBq/cc)の変動を5mm以下の精度で検出可能という結果を得た。TOF(Time of Flight)に関するシミュレーションを行い、効果を評価した。4次元分割に関する研究を進め、膵がんでの4次元強度変調放射線治療の臨床研究を開始した。
電子線を任意の部位に加速する技術は深部臓器でのピンポイント照射精度の上で限界があることが示された。レーザー加速による陽子線治療を離床したスポットスキャン法での眼腫瘍の治療に関するモンテカルロシミュレーションを行い、適切な線量分布を得ることが可能であることが判明した。
低酸素細胞に特異的に取り込まれる放射線医薬品を、4次元定位放射線治療における癌組織の部位を示すマーカーとして利用可能かどうかを調べるために、18F-MISOの利用に関する前臨床試験を行い十分可能であることが示された。半導体PETや高精度MRIでの低酸素細胞の把握が治療計画に利用可能であることが示唆された。
