快速自旋回波脉冲序列的设计与实现

Design and Implementation of Fast Spin Echo Sequence

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。

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.
