20100090697 | METHOD OF PERFORMING MRI WITH AN ATOMIC MAGNETOMETER - A method and apparatus are provided for performing an in-situ magnetic resonance imaging of an object. The method includes the steps of providing an atomic magnetometer, coupling a magnetic field generated by magnetically resonating samples of the object through a flux transformer to the atomic magnetometer and measuring a magnetic resonance of the atomic magnetometer. | 04-15-2010 |
20100219827 | ULTRA-LOW FIELD NUCLEAR MAGNETIC RESONANCE AND MAGNETIC RESONANCE IMAGING TO DISCRIMINATE AND IDENTIFY MATERIALS - 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, T1ρ, 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. | 09-02-2010 |
20120001631 | ULTRA-LOW FIELD NUCLEAR MAGNETIC RESONANCE METHOD TO DISCRIMINATE AND IDENTIFY MATERIALS - 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. | 01-05-2012 |
