Outline of Final Research Achievements

We aimed to develop an ultra-low-field (ULF) NMR/MRI system, which will be basis of functional MRI microscopy in the future. In this study, an ultra-sensitive SQUID magnetic sensor, which has extremely high sensitivity in low frequency range, which correspond to Larmor frequency in ULF, was used in the ULF NMR/MRI system. Using the system, we showed that the signal amplitude and line width of NMR signal in ULF increased and decreased with the static field intensity, respectively. Achievement of MRI in ULF was also demonstrated. We also studied possibility of realization of ULF NMR/MRI in normal environment, by combining robust SQUID and noise cancelling techniques.
