Abstract

Purpose: Conventional gamma‐ray detector, PET and SPECT, have the limitation of energy. These limitations are major problems of studying for a new medical imaging. Therefore, we have developed the new imaging detector which is an electron‐tracking Compton camera (ETCC). We show results of the update ETCC system and show the imaging Result of 95m‐Tc which is one of the targets for new imaging reagents. Methods: The ETCC has a wide energy dynamic range and wide field of view. Also the ETCC can detect recoil‐electron tracks which are generated from Compton scattering. We have developed the new ETCC system which have been modified the logic of catching the electron tracks and have better performance compared with old system. The 99m‐Tc is the most important radioisotopes which are used in nuclear medicine. However, the lifetime of the 99m‐Tc is 6 hours, it may not be possible to use imaging reagent for using antibody reaction because of accumulation time. The technetium, however, have many isotopes and many energy peaks. If we can reconstruct gamma rays which have various energy peaks, imaging technology for nuclear medicine will progress. The 95m‐Tc (204, 582, 835 keV ) is one of the targets for a new imaging reagent. In this presentation, we show the new ETCC system performance and 95m‐Tc imaging results. Results: ETCC achieved a wide energy dynamic range (200–1300keV) and wide field of view. We could catch the recoil electron tracks clearly using new ETCC system, and we succeeded in imaging of the 95m‐Tc. Conclusion: We have developed the ETCC for new medical imaging device and succeeded in imaging of the 95m‐Tc. We started to develop the ETCC which can image the mouse within 30 min. Thus, this detector has the possibility of new medical imaging.
