Outline of Final Research Achievements

We have been developing a real-time RI imaging system (RRIS), which is an radioisotope live imaging system. For RRIS imaging, plants need to be fixed to a plate scintillator. On the other hand, since plants grow three-dimensionally, fixing plants to a plate in two dimensions damages them. Therefore, we aimed to develop a techniques that enables radioisotope imaging without damaging the plants using powder scintillator. As a result, we were able to perform radioisotope live imaging on plants that were difficult to image with RRIS. In addition, many new scintillators were discovered in this study.

Academic Significance and Societal Importance of the Research Achievements

これまでのRRISではイメージングが困難であった植物においてもRIライブイメージングをすることができるようになったことで、研究の対象となる植物種が広がった。さらには、本研究で発見した多数の新規シンチレータは、RRISのみならず、様々なRI検出器への適用が可能であり、新規のRI検出器の開発が期待できる。現在は、民間企業と共同研究を進めているところである。
