| Outline of Final Research Achievements |
The purpose of this project is to develop an MRI transmitting and receiving head coil that can be integrated with high-resolution PET detectors. Using a prototype head coil, we tried to optimize the position of the shield boxes in proximity to the head, and to reduce interaction between PET and MRI. After modifying the shield boxes for the PET system and the coil design, an MRI coil integrated with one-ring PET detectors was developed. Simultaneous measurement of PET and MRI by this system provided sufficient useful information to support its clinical applicability.
