摘要/Abstract

摘要：

介绍了快速自旋回波成像方法（FSE）在医学磁共振成像（MRI）系统上的实现. 提出了一种简单的预扫描方案，可以有效克服FSE成像方法的固有缺陷. 软件系统的预扫描定制方案，使得本系统可以适应于不同的预扫描要求，谱仪的无关性保证了本系统可以很方便地附加在任何谱仪上. 最后给出了FSE方法在DRX谱仪上的实现和在200 mT系统上获取的实验结果.

Abstract:

The FSE imaging method was implemented on a clinical MRI scanner. A simple FSE prescan scheme, which could overcome the inherent defect of FSE, was proposed. Customizing method used in software system could control all kinds of prescan combination demanded by MRI experiment. The software system is compatible with most of the NMR spectrometers, and its application on a DRX spectrometer and a 200 mT system was demonstrated.

Key words: MRI system, FSE, Prescan
