Outline of Research at the Start

本研究では、革新的な内部被ばく推定法を提案し、核医学の新たな個別化医療を実現することを目的とする。小型線量計 を複数、患者体表面に貼付し、線量計の測定値から逆問題を解くことにより、体内の複数臓器の放射能を同時に推定、これにより、個人の臓器線量、実効線量を求めるものである。個人個人の体格の違い、臓器の位置の違いを考慮して、個別に数学ファントムを構築し、また、線量計で測定された時系列データから各臓器内の放射能の今後の変化を予想する方法を提案する。さらに、さまざまな核医学核種に対応し、リアルタイムにデータを収集できる新しい小型線量計を開発する。

Outline of Final Research Achievements

The purpose of this research is to propose an innovative method for estimating internal exposure in nuclear medicine examinations using a few number of small dosimeters, and to realize new personalized medicine in nuclear medicine. By building a model tailored to each subject's individual physique, we succeeded in determining the individual's exposure dose during PET examinations. We have also developed a new compact dosimeter, making it possible to wirelessly collect information from multiple dosimeters at once.
By using the method developed in this study, it will be possible to estimate an individual's internal exposure dose easily and inexpensively.

Academic Significance and Societal Importance of the Research Achievements

現在、世界的に診断と治療を融合させたセラノスティクスが核医学において潮流となりつつある。セラノスティクスにおいては、各個人の核医学画像から線量を推定するが、従来の方法は、標準人を想定したモデルを利用しており、精度が高くない。また複数の撮像を必要としており、医療経済的にも好ましくなかった。本研究成果はこの状況を打破する新たな治療戦略を提供するものであり、精度の高い個別化医療を安価に提供できるようになるであろう。
