Abstract

Nuclear magnetic resonance imaging (MRI) is widely used as tomographic image inspection in clinical. MRI has many advantages such as obtaining tomographic images by non-exposure. However, it requires a strong magnetic field (0.4 to 3 T in general), so it also has disadvantages such as large size and high cost. If we use extremely low magnetic field as low as the earth B-field for MRI may be useful. In this study, we demonstrated the increase of nuclear magnetic resonance signals by spin hyperpolarization by spin exchange optical pumping for xenon in an extremely low magnetic field.
