Event Abstract Back to Event Low-field magnetic resonance imaging of high sensitivity and spatial resolution using high-Tc superconducting quantum interference devices Hong-Chang Yang1*, Shu-Hsien Liao1, Hsin-Hsien Chen2, Ming-Jye Chen1, Herng-Er Horng2 and Shieh-Yueh Yang2 1 National Taiwan University, Department of Physics, Taiwan 2 National Taiwan Normal University, Institute of Electro-optical Science and Technology, Taiwan In this work, nuclear magnetic resonance and magnetic resonance imaging (NMR/MRI) in microtesla magnetic field using high-Tc SQUID magnetometer is presented. In the proposed NMR/MRI detection scheme, the nucleus spin procession was inductively coupled to the SQUID magnetometer via a flux transformer. According to the proposed detection scheme, both the SQUID and the input coupling coil were placed inside a high-Tc superconducting vessel which shielded environmental noises and set the SQUID in a stable operation condition.. Applying a pre-magnetized field of 50 mT, a gradient field of 24.6 uT/m and a uniform measurement field of 101 uT, proton MRI of water, and bell pepper with a spatial resolution given by dx = 2*pi*df/(r*G) = 1 mm in proton MRI, where r = 42.58 kHz/mT, was demonstrated. The MRI system of high spectral resolution and high sensitivity will be of great interest for a study of biological imaging.
