| Outline of Final Research Achievements |
Ultra-low field magnetic resonance imaging (ULF-MRI) is receiving increased attention as a novel measurement of MRI in the recent decade. The purpose of this study is to build a practical measurement technique of ULF-MRI.
The nuclear magnetic resonance (NMR) signal in the ultra-low magnetic field is extremely weak, so that the superconducting resonance quantum interference device (SQUID) sensor has been employed for signal detection. In this study, we developed a detection system based on an induction coil which can be used at room temperature. The feasibility of the practical ULF-MRI system were demonstrated by some MRI measurements including imaging and T1 relaxation time measurements.
