AI Technical Summary

Technical Problem

In existing technologies, NMR measurement systems suffer from a spin-enhanced state during startup and application, which presents a difficult-to-solve technical problem. This includes the spin magnetization deviating from the equilibrium state during startup, leading to a decrease in measurement accuracy and difficulty in rapid recovery.

Method used

By applying an HF pulse before startup or after interference, the x-component of spin magnetization is brought to a balanced state. The balance of spin magnetization is then quickly restored by the combined control of the compensation coil and the HF coil.

Benefits of technology

This method enables rapid recovery of the spin magnetization equilibrium state, improving the start-up speed of NMR measurements and the measurement accuracy under gradient and decoupling conditions.

Abstract

The invention relates to a method for operating an NMR measurement system having a main field magnet for generating a static main magnetic field B0 in the z-direction, a measurement HF coil for exciting a core spin of a measurement substance, an NMR lock regulator for detecting field disturbances and for generating a correction field by means of a compensation coil, the lock regulator being carried out, the invention relates to a method for measuring the spin of a reference substance, comprising a locking adjustment during which the spin of the reference substance is excited, characterized in that the spin magnetization M of the reference substance is brought from an unbalanced state into a state in which the x component Mx of the spin magnetization has an equilibrium value Mxeq by applying an HF pulse (1, 1 '), the x component Mx of the spin magnetization being oriented in an x-direction perpendicular to the z-direction, whereby improved measurement accuracy is achieved.
