7T超高磁場MRIにPET機能を後付けするRFコイル一体型放射線検出器の開発

本研究旨在开发用于7特斯拉核磁共振成像系统的正电子发射断层扫描（PET）脑插片。我们已经为此目的开发了射频（RF）线圈。射频线圈包括PET检测器模块作为一个组成部分。研制了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一些性能测试。我们还试验了几种PET线圈的设计配置。利用第二年的预算，我们将为这些线圈开发电路。在此阶段之后，我们将在爱知县国家生理科学研究所（NIPS）的7特斯拉MRI设备上进行PET和MRI成像实验。这项合作研究将于2023年底进行。一篇科学论文正在审稿中。

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.
