摘要:

开发了基于核磁共振(NMR)谱仪的医学MRI软件系统. 本文主要介绍了数据采集及处理系统,扫描方案的设计可以用于几乎所有的磁共振成像实验,预扫描定制方案解决了不同实验应有不同的预扫描这一要求,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. 最后给出了软件系统跟DiSpect谱仪相联并在0.35 T系统上获取的实验结果.

关键词: 磁共振成像, 数据采集系统, 软件

Abstract:

A software system is developed for use in low-field medical MRI systems. In this paper, the data acquisition and processing systems in the software are introduced. The software allows scan schemes that could meet the requirements of almost all commonly-used MRI experiment. The prescan customizing method could control all kinds of scan schemes. The software is spectrometer-independent so that it can be implemented conveniently in different types of spectrometers. We implemented this software system in a Dispect spectrometer and the experimental results acquired on a 0.35 T system are presented.

Key words: MRI system, data sampling, software
