先前的研究表明，脉冲功能性磁刺激可以以最佳强度和频率激活脑组织。传统的刺激线圈总是设置为8字形或亥姆霍兹。但这些线圈产生的磁场在目标周围是均匀的，其磁刺激性能仍需改进。本文提出了一种新型的刺激线圈，以缩小刺激区，增强刺激强度。此外，电磁场分布的计算和测量。基于数值模拟，提出的线圈相比，传统的线圈类型。此外，还分析了直径和相交角等因素的影响。结果表明，与8字形线圈相比，所提出的线圈具有更好的性能。因此，这项工作提出了一种新的方法来设计刺激线圈的经颅磁刺激。
Previous research showed that pulsed functional magnetic stimulation can activate brain tissue with optimum intensity and frequency. Conventional stimulation coils are always set as a figure-8 type or Helmholtz. However, the magnetic fields generated by these coils are uniform around the target, and their magnetic stimulation performance still needs improvement. In this paper, a novel type of stimulation coil is proposed to shrink the irritative zone and strengthen the stimulation intensity. Furthermore, the electromagnetic field distribution is calculated and measured. Based on numerical simulations, the proposed coil is compared to traditional coil types. Moreover, the influential factors, such as the diameter and the intersection angle, are also analyzed. It was demonstrated that the proposed coil has a better performance in comparison with the figure-8 coil. Thus, this work suggests a new way to design stimulation coils for transcranial magnetic stimulation.
