摘要
通过这篇学术文章,对全国各地技术机构正在进行的检测核磁共振成像(MRI)系统中如何正确操作、正确处理数据及客观评价起到积极的作用。所采用的方法是北美放射物理学会(AAPM)和美国国家电气生产厂家标准(NEMA)推荐的方法。从近几年来对北京地区新安装的、使用中几十台磁共振成像系统(MRI)进行了检测结果表明,采用AAPM建议书和NEMA标准所规定的方法对中国开展核磁共振成像(MRI)系统中图像的检测是可行的,也是必须的。对我们今后正在制定国家级《核磁共振成像系统(MRI)检测规范》是非常有益的。
This research makes an active effection in how to operate MRI and conduct the datas and objectively access it,which will appear during the examine of MRI,that being proceeded in many techinal organs in our country.The method we used is recomended by AAPM and NEMA recent years,we exanined MRI which are new install or in using, its demonstrate that it is feasible and necessary to examine the picture of MRI in china by suggestion of AAPM and criterion of NEMA.It's valuable for us to stipulate for national 《Technical Specification of Measurement Nuclear Magnetic Resonance Image (MRI)》.
