摘　　要：为了优化磁刺激线圈设计,解决磁场聚焦性不足的问题,并为以后经颅磁刺激(TMS)线圈结构的进一步改进提供设计依据,将经颅磁刺激技术更好的应用到临床治疗和科学研究中,在深入查阅研究相关文献的基础上,介绍了现有的几种典型线圈结构,并对经颅磁刺激中使用的不同线圈以及其在空间中产生的电场和磁场的强度和分布进行了分析、对比,研究了不同线圈结构的聚焦性和应用场合。研究结果表明:现有的改进型线圈结构虽然都具有自身的优点,并且在聚焦性或刺激深度方面大大超越了传统线圈,但结构过于复杂,能耗过高,实用性不足,在需要精确刺激靶点区域的情况下仍然不能提供令人满意的空间分辨率,因此经颅磁刺激线圈结构的进一步优化设计仍然具有很大的提升空间。In order to optimize the coil design, improve the deficient focality of induced magnetic field, provide further support for the development of coil design and apply the transcranial magnetic stimulation （TMS） to clinical and scientific applications effectively, analysis and comparations of different types of coil designs as well as their induced magnetic and electric filed were made on the basis of reviewing the current literature. Their focality and applications were also discussed.The research results indicate that, even though scientists proposed different kinds of coil designs, complicated configuration and high energy consumption make these new designs possess poor practicability. Most of them fail to supply satisfied spatial resolution when precise stimulation is needed. There is still a long way to optimize the coil design.
