摘要

本研究采用Shinnar-Le Roux算法设计MRI射频脉冲，以减小Bloch方程的非线性影响。通过比较SLR脉冲切片与SINC脉冲切片的差异，进行了一些MRI实验，验证了Shinnar-Le Roux算法的有效性。实验结果表明，单反脉冲的切片轮廓波纹较小，比SINC脉冲更均匀。通过减少切片的干扰，单反脉冲可以在很大程度上提高成像质量。

Slice Profile Experimental Comparison of Shinnar-Le Roux Pulse and SINC Pulse in Magnetic Resonance Imaging

In this study, Shinnar-Le Roux algorithm is used for designing the radio frequency pulses in MRI in order to reduce the nonlinearity effect of the Bloch equation. Some MRI experiments are conducted to show the effectiveness of Shinnar-Le Roux algorithm by comparing the difference between SLR pulsed slice profile and SINC pulsed slice profile. The experimental results indicates that the slice profile of SLR pulse has smaller ripples and is more uniform than SINC pulse. By reducing the interference of slices, the SLR pulse can improve the imaging quality to a great extent.
