摘　　要：介绍一种用于计算14 T MRI磁场位形的高精度方法。首先将单匝卢瑟福电缆视作一个微型线圈,以单匝电缆为基本载流单元,计算其磁场分布,再根据磁场叠加原理,求得整个MRI磁体的磁场位形。结果表明,该方法与OPERA计算结果一致。An algorithm was proposed with Rutherford cable used as the basic unit to analyze and calculate the magnetic field configuration of 14 T MRI.Magnetic field configuration of single turn cable was calculated at first,then magnetic field configuration of MRI magnet was calculated based on the superposition principle of magnetic field.The results indicate that the result from this method is consistent with one of OPERA.
