This research aims at developing positron emission tomography (PET) brain insert for a 7 Tesla MRI system. We have already developed radiofrequency (RF) coils for this purpose. The RF coil includes PET detector module as an integral part. Four microstrip transmission line RF coils have been developed. We have performed coil optimization test and few performance tests at laboratory. We have also experimented several design configurations for the PET coils. With the second year's budget, we will develop circuits for these coils. After this stage, we will perform PET and MRI imaging experiments at the 7 Tesla MRI facility in the National Institute for Physiological Sciences (NIPS) in Aichi. This collaboration study will be conducted by the end of 2023. A scientific paper in under review now.

这项研究旨在开发用于 7 特斯拉 MRI 系统的正电子发射断层扫描 (PET) 大脑插入物。我们已经为此开发了射频 (RF) 线圈。 RF 线圈包括 PET 探测器模块作为一个组成部分。已开发出四种微带传输线射频线圈。我们在实验室进行了线圈优化测试和少量性能测试。我们还尝试了几种 PET 卷材的设计配置。根据第二年的预算，我们将为这些线圈开发电路。此阶段结束后，我们将在爱知县国立生理科学研究所 (NIPS) 的 7 Tesla MRI 设施中进行 PET 和 MRI 成像实验。这项合作研究将于 2023 年底进行。目前正在审查一篇科学论文。
