Abstract
The invention provides a high resolution proton nuclear magnetic reonance and imaging (NMR/MRI) in microtesla magnetic fields by using high critical temperature (high-T) superconducting quantum interference device (SQUID) magnetometer via a flux transformer. Both the SQUID and the input coupling coil are installed inside a superconducting vessel which shields environmental noise and set the SQUID in a stable operation condition. The present invention also offers the advantages of preserving the NMR signal even if the sample is far away from the SQUID detector.
