摘要

地球的核磁共振场可以用来估计不同液体中的质子弛豫参数。在液体样品中，由于地球磁场的作用，它可以定量质子弛豫持续时间t1和t2，以及自扩散系数D。通过分析大范围的液体样品，证明仅根据这些特征来区分液体是可行的。本文研究了是否有可能利用地球磁场核磁共振(EFNMR)来正确和实际地量化t1和t2以及自扩散系数d。这些发现为进一步研究利用EFNMR来确定弛豫参数铺平了道路。利用地球磁场获得了50ml甲苯溶剂在低频下的二维1H NMR图像。

Application of nuclear magnetic resonance/magnetic resonance imaging techniques to estimate proton relaxation parameters in various solvent at Earth field

The nuclear magnetic resonance (NMR) field of earth may be utilized to estimate proton relaxation parameters in different liquids. In liquid samples, it can quantified proton relaxation durations T 1 and T 2 , along with the self-diffusion coefficient D, thanks to the magnetic field of the Earth. It was proved that it is feasible to distinguish between liquids based only on these characteristics by analyzing a wide range of liquid samples. In this paper, it was investigated whether it is possible to utilize Earth’s magnetic field Nuclear Magnetic Resonance (EFNMR) so as to correctly and practically quantify T 1 and T 2 along with the self-diffusion coefficient D. These findings pave the way for additional research into the use of EFNMR for the determination of relaxation parameters. It was acquired two-dimensional 1H NMR images of 50 ml of toluene solvent at low frequencies using the magnetic field of the Earth.
