NMR spectroscopy data recovery method and apparatus |
摘要 |
NMR spectroscopy data recovery methods and apparatus for improving the quality of an NMR spectrum are disclosed. The NMR spectrum is improved by acquiring more than the half spin-echo data signal and using an iterative numerical method to reconstruct the missing data points of the corresponding full symmetrical spin-echo data signal. The method includes filtering the initial data signal to extract a low-resolution phase term. The low-resolution phase term is used to form a phase-constrained initial data signal, which is Fourier-transformed to obtain a reconstructed data signal. The reconstructed data signal is modified to include the original spin-echo signal data. The formation of the reconstructed spin-echo data signal and subsequent modification is iterated until convergence is obtained. The reconstructed data signal is then Fourier-transformed to form a reconstructed NMR spectrum.
