提出了一种将压缩感知(CS)方法和最优内插逼近相结合的二维核磁共振波谱快速重建方法。我们定义了一个权函数,它具有与CS方法重建的2D核磁共振谱相同的波形。然后,该方法利用由权函数得到的最优内插函数,通过最优内插逼近重建二维核磁共振波谱。实验结果表明,对于101种不同的采样模式,新方法都能重建出更准确的二维核磁共振波谱。
We present a new fast reconstruction method for 2D NMR spectrum by combining the compressed sensing (CS) method and the optimum interpolation approximation. We define a weighting function that has the same waveform of the 2D NMR spectrum reconstructed by the CS method. Then, the proposed method reconstructs the 2D NMR spectrum by the optimum interpolation approximation with the optimum interpolation functions derived from the weighting function. Experimental results show that the new method always reconstructs a more accurate 2D NMR spectrum for 101 different sampling patterns.
