摘要: 本文用Bloch方程模拟了BURP族脉冲[1-3]和高斯串族脉冲[4,5](Gaussianpulsecastales)的激发轮廓,系统地比较了这两类脉冲的选择性及其对射频场非均匀性的依赖性,给出了选择性最佳的脉冲。

Abstract: The excitation profile of BURP family pulses and Gaussian pulse cascades is simulated based on the Bloch equation. The selectivity of the various Dulses from these two kinds of pulses are compared systematically.The effect of inhomogeneity of the radiofrequency field B1 on excitation profile is also simtilated. The pulses with optimum selectivity are suggested.
