Preliminary study on Ultra-Low Field (ULF) Magnetic Resonance Imaging (MRI) system with a high-temperature superconductor (HTS) SQUID for food contaminant inspection was conducted. The ULF SQUID-MRI system for food inspection, which we previously proposed, used a tuned circuit to detect a magnetic field at Larmor frequency. However, since the bandwidth becomes narrower by the tuned circuit as the MR signal frequency decreased, it was necessary to elongate the signal acquisition time. Therefore, it was difficult to measure the MR signal of food with a short relaxation time, such as oil, because of the longer echo time. We describe a ULF SQUID-MRI system using a non-resonant Cu wound flux transformer to image food with a shorter relaxation time in this paper. As a result, T1-weighted images of samples containing water and mineral oil could be obtained by varying the polarizing time. |
