摘　　要：射频场的均匀性是决定磁共振成像性能的重要指标，它由线圈的结构及几何尺寸所决定．论述了鞍型线圈的磁场分布特性，并给出了最佳设计方案．根据最佳结构设计线圈，能获得十分均匀的射频场，从而提高图象质量．The uniformity of the RF magnetic field is very important for MRI. It is determined by the coil structure and dimension. This thesis deals with the theoretical principles of magnetic field distribution. The optimum design of saddle shaped coil is given. A uniform magnetic field is produced by the use of such a structure. So higher image quality will be obtained.
