| Outline of Final Research Achievements |
We developed innovative imaging technologies for X-rays and gamma rays for wide applications to medicine and environmental survey. We constructed a PC-CT system that enables high-speed coloring of each X-ray photons. Multi-color imaging of multiple contrast and anticancer agents was successfully demonstrated under 1/100 dose of conventional CT scan. For gamma rays, we developed the world’s smallest Compton camera that applied for a three-dimensional multicolor imaging of living mice. The camera was further applied to the nuclear medicine treatment to visualize drug delivery for four trial patients. In proton therapy, proton dose was directly imaged by using prompt gamma rays (4.4 MeV) and a novel method of measuring nuclear reactions was proposed. In environmental measurements, we used a commercial drone for rapid 3D visualization of radioactive substances (137Cs) from the sky. We finally developed a super-resolution technology to sharpen the obtained radiation images.
