Abstract

As a noninvasive neuromodulation technique, transcranial magnetic stimulation (TMS) has already exhibited a great impact in clinical application and scientific research. This study presents a finite element method-based simulation of the Halo-V assembly (HVA) coil placed on the five-shell spherical human head model to examine the distributions of induced electric and magnetic fields. The performance of the designed HVA coil is evaluated by comparing the simulation results with the commercially available Halo-FO8 (HFA) assembly coil and standard single coils including the Halo and V coils. The simulation results indicate that the HVA coil shows an improved focality in terms of electric field distribution than the other single and assembly stimulation coils. Additionally, the effects of a magnetic shield plate and magnetic core on the designed HVA coil are investigated. Results indicate that the magnetic shield plate and magnetic core are proficient in further improving the stimulation focality. Therefore, the HVA TMS coil results in a safe and effective stimulation with enhanced focality of the target region as compared to the existing assembly coil.

Halo-V组合线圈经颅磁刺激脑组织感应场分析。

经颅磁刺激(transcranial magnetic stimulation, TMS)作为一种无创神经调节技术，已经在临床应用和科学研究中显示出巨大的影响。本文提出了一种基于有限元法的仿真方法，将Halo-V组件(HVA)线圈放置在五壳球形人体头部模型上，以研究感应电场和磁场的分布。通过将仿真结果与市售的Halo- fo8 (HFA)组件线圈和包括Halo和V线圈在内的标准单线圈进行比较，对所设计的HVA线圈的性能进行了评估。仿真结果表明，高压伏安线圈在电场分布上的聚焦性优于其他单线圈和组合线圈。此外，还研究了磁屏蔽板和磁芯对设计的高压高压线圈的影响。结果表明，磁屏蔽板和磁芯能够有效地进一步提高刺激的聚焦性。因此，与现有的装配线圈相比，HVA TMS线圈可以实现安全有效的刺激，并增强了目标区域的聚焦。
