快速自旋回波脉冲序列的设计与实现

摘要

Fast spin - echo sequence is a sequence for reducing data acquisition time and accelerating the speed of imaging. It is a necessary fast imaging sequence in magnetic resonance scanner at home and abroad. We made research on the principle, design and programming of fast spin - echo sequence. The results of SE sequence and fSE sequence were compared and analyzed. It provides an important reference on the independent research and development on the MR scanner in our country.%快速自旋回波序列可减少磁共振成像的数据扫描时间,提高成像速度,是国内外MR扫描仪必备的快速序列之一.本研究对快速自旋回波序列的设计、编程和实现方法进行了研究,对快速自旋回波序列与自旋回波序列的成像结果进行了比较和分析.该方法为国内MR扫描仪的自主研发提供了重要参考.
