摘要
介绍了常用的磁共振成像加速方法,其中并行成像尤为重要,因为它可以和其他加速方法互补;还介绍了5种常见的并行成像方法:利用局部灵敏度的部分并行成像、灵敏度编码、空间谐波同时获取、泛化自校正部分并行获取、与基于阵列线圈灵敏度的并行编码与复原。最后,讨论了这5种方法的互相联系,以及在工业上的应用,并展望了动态成像和非笛卡尔坐标扫描的发展。
In this paper,the common approaches for expedition of magnetic resonance imaging are investigated,among which the parallel imaging method is most important due to its natural complementary ability to other acceleration approaches.Then,five popular parallel imaging methods are discusses including the PILS,SENSE,SMASH,GRAPPA,and SPACE LIP.At final,the correlation between and the industrial applications of those methods are reviewed,with exploitation of the dynamic imaging and non-Cartesian scan pattern.
