| Outline of Final Research Achievements |
X-ray CT is a basic technology to support the modern healthcare, but a large radiation dose by X-ray CT is a serious issue. To overcome the difficulty, we newly developed an X-ray CT system using multi-pixel photon counters (MPPCs), instead of photodiodes which have been used for conventional X-ray CT. We found that the MPPC CT system can drastically reduce the radiation dose by a factor of ~100 compared with the conventional X-ray CT, thereby indicating great potential for low-dose CT imaging. Furthermore, we demonstrated the multi-color X-ray CT imaging and successfully developed a multi-channel MPPC array system. These results show that we succeeded in establishment of the core technology for future low-dose and multi-color X-ray CT using MPPCs.
