  • Ultra-low field nuclear magnetic resonance and magnetic resonance imaging to discriminate and identify materials
    Patent number: 8390286
    Abstract: Method comprising obtaining an NMR measurement from a sample wherein an ultra-low field NMR system probes the sample and produces the NMR measurement and wherein a sampling temperature, prepolarizing field, and measurement field are known; detecting the NMR measurement by means of inductive coils; analyzing the NMR measurement to obtain at least one measurement feature wherein the measurement feature comprises T1, T2, T1?, or the frequency dependence thereof; and, searching for the at least one measurement feature within a database comprising NMR reference data for at least one material to determine if the sample comprises a material of interest.

  • ULTRA-LOW FIELD NUCLEAR MAGNETIC RESONANCE METHOD TO DISCRIMINATE AND IDENTIFY MATERIALS
    Publication number: 20120001631
    Abstract: An ultra-low field (ULF) nuclear magnetic resonance (NMR) and/or magnetic resonance imaging (MRI) system can be used for rapid identification and discrimination of materials, e.g., liquid in opaque containers and/or materials in or on human bodies. The system utilizes the ability of ULF NMR/MRI to measure NMR parameters in magnetic fields that can be easily changed in field strength and orientation.
