摘要
影响核磁共振(MR)图像质量最基本的部分为磁体,在评价核磁共振扫描仪的众多参数中,主磁场的均匀性是最基本也是最重要的一个衡量指标,该文阐述磁场均匀性对核磁共振成像质量的影响和磁场均匀度测量方法。
The most fundamental part influencing the quality of magnetic resonance imaging (MRI) is the magnetic body. Among the many parameters for evaluating the nuclear magnetic resonance scanner,the most important one is the main magnetic field homogeneity,it is also the most basic measure index. The effect of magnetic field homogenous level on the MRI quality and measuring approach of magnetic resonance field homogenous level are elaborated in this paper.
