| Abstract(in English) | Nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI) in ultra-low field (ULF) using SQUIDs have attracted attention in recent years because the systems do not require complicated apparatus such as superconducting magnets Thus it can be compact, easy to handle, and inexpensive We have developed an ULF-NMR/MRI system utilizing an HTS-SQUID for an application of contaminant detection in foods In this work, we measured NMR signals from water samples with or without various contaminants, such as stainless steel (SUS304), aluminum, and glass balls using the system In the case of the magnetic contaminants, the whole NMR signal intensity was reduced compared to that from the sample without the contaminant due to the remnant field of the contaminant One-dimensional (1D) MRIs of the samples with non-magnetic contaminants were also measured In the 1D-MRIs, changes of the MRI spectra were measured at center frequency, which corresponded to positions of the contaminants in the sample These results show that the feasibility of the system to detect various contaminants in foods |
