Outline of Final Research Achievements

In the midterm of this research, my affiliation has changed. However, thanks to the warm understanding by the collaborators of ISAS/JAXA and the supervisor of OIST, I have continued this research after moving to OIST. Finally, I completed the prototype of Compton cameras and installed it into the radiation controlled area in OIST for 3-D imaging study with unsealed liquid radioisotopes. Hands-on imaging experiment is now ready. This research has generated new collaborative research among ISAS/JAXA, The University of Tokyo and OIST.
