| Outline of Final Research Achievements |
To improve the sensitivity of MRI, we applied the idea of signal up-conversion from radio-frequency to optical regimes to MRI. First, we have developed an MRI system from scratch using an existing 7 T superconducting magnet, demonstrating MRI of water in a glass tube and of fruits. In addition, we have designed and fabricated a radiofrequency-to-light signal transducer which is compact enough to be put inside the superconducting magnet with a bore size of ca. 70 mm, and successfully detected the optical signals that was transduced from the electrical signals. We also invented a new method for acquiring MRI without requiring wide-band detectors, showing a future direction toward unification of MRI and optical signal detection.
