LOW FIELD NUCLEAR MAGNETIC RESONANCE APPARATUS AND LOW FIELD NUCLEAR MAGNETIC RESONANCE METHOD

摘要

PURPOSE: A low-field nuclear magnetic resonance apparatus and method are provided to obtain a magnetic resonance signal through signal amplification using dynamic nuclear polarization. CONSTITUTION: A low-field nuclear magnetic resonance apparatus comprises a DNP(dynamic nuclear polarization) amplification unit(161), a sensor unit(111), and a detecting magnetic field coil(172). The DNP amplification unit amplifies nuclear magnetization of hydrogen atom using a DNP material. The sensor unit measures the magnetic resonance signal of an object using a SQUID sensor or nuclear magnetometer. The detecting magnetic field coil applies a detecting magnetic field to the object.
