Outline of Final Research Achievements	The purpose of this study was to develop an RF coil to obtain a high spatial resolution MR image of local brain region at 7 Tesla MR scanner. A performance of RF coil is a key factor in obtaining the high spatial resolution MR image. To develop a high-performance RF coil, I worked at building a multi-channel RF coil. At this step, it was found that a structure of RF shield around the RF coil influenced a resonant characteristic and the performance of individual RF coil. Therefore, I investigated a proper structure of RF shield to improve a single RF coil's performance with EM simulation. As a result, an effective structure of RF shield to increase the performance of single RF coil was found.
