| Outline of Final Research Achievements |
Astatine-211 is a promising radionuclide for targeted radiotherapy. It is important to acquire an image of the distribution of targeted radiotherapeutic agents in a patient's body for optimization of treatment strategies. We proposed to image At-211 quantitatively with high-energy photons to overcome some problems in conventional planar gamma camera or single-photon emission computed tomography imaging. We performed an imaging experiment of a point-like At-211 source using a Compton camera, and demonstrated the capability of imaging At-211 with the high-energy photons for the first time.
