Method for reducing the coupling between excitation and receive coils of a nuclear quadrupole resonance detection system
First Claim
1. A method for reducing coupling of coils in a nuclear quadrupole resonance detection system that is comprised of one or more excitation coils and one or more high temperature superconductor receive coils, wherein the method comprises shifting, during excitation, the resonance frequency of the receive coil(s) to thereby reduce coupling between the excitation coil(s) and the receive coil(s).

Abstract
This invention relates to a method for improving the performance of a nuclear quadrupole resonance detection system by reducing the coupling between one or more excitation coils that provide a radio frequency magnetic field that excites quadrupole nuclei, and one or more high temperature superconductor receive coils that detect the resulting nuclear quadrupole resonance signal.
