SQUID DETECTING NUCLEAR MAGNETIC RESONANCE AND IMAGING IN VERY FEEBLE MAGNETIC FIELD

摘要

PPROBLEM TO BE SOLVED: To provide a method and an apparatus for detecting nuclear magnetic resonance (NMR) in a sample. PSOLUTION: This method and apparatus is a method and an apparatus for high resolution proton nuclear magnetic resonance and imaging (NMR/MRI) which detects NMR from a sample through a magnetic flux transformer, using a high critical temperature (high Tc) superconducting quantum interference device (SQUID) fluxmeter in a microtesla magnetic field. Both SQUID and an input coil shield environmental noise and are placed in a superconducting container which keeps SQUID in a stable operating state. The method and apparatus includes an advantage of maintaining a NMR signal even when a sample is distant from a SQUID detector. PCOPYRIGHT: (C)2011,JPO&INPIT
