| Outline of Final Research Achievements |
We developed a gamma-ray imager based on the requirements of our research projects and nuclear medicine. We applied the technology based on a high-resolution CdTe imager to in vivo imaging of cancer-bearing mice. We succeeded in simultaneously visualizing the accumulation of three different RI compounds in the microstructure of the mouse pharynx with high spatial resolution. For image analysis, the analytical technique of X-ray observation of supernova remnants was applied. A wide-field imager was developed to study in vivo pharmacokinetics and successfully visualize At-211 accumulation in tumors, which could not be determined with the conventional SPECT system. We also applied our technology to non-destructive element analysis and polarization measurement in atomic physics and nuclear physics.
