| Outline of Annual Research Achievements |
In two years research period, I could develop a radio frequency (RF) coil for positron emission tomography (PET) insert for magnetic resonance imaging (MRI) system. The developed coil has been selected by my institute for a patent and we successfully have submitted a patent already, both US patent and Japanese Patent. The RF coil is a microstrip type multichannel coil for parallel transmission and reception, that is mostly used in the ultra-high field (UHF) MRI systems, like a 7 Tesla MRI. I also did study using RF shielding materials for different prototype models of PET, like, full-ring and partial-ring oval-shaped and cylindrical PET, RF floating PET for MRI. The floating PET insert study has a collaboration with Professor Craig S. Levin of Stanford University. Part of this grant has been used for English editing for four journal publications. I attended four international conferences in this period to present both oral and poster presentation. With some remaining money, I purchased different mesh-type shielding materials to optimize shielding design for PET insert for MRI. I had to divert my research from the planned wireless PET design because of the unavailability of the Wigig transceiver chip, which was the center point of this research. After many tries, I found that it is not available for research study and only available for commercial use, like in laptop PC of a company. Developing a custom wigig chip is possible, but would require large-scale funding and different collaboration. I hope to pursue this kind of study in future. Thank you very much.
