【摘要】 磁刺激是利用变化磁场产生的感应电场作用于可兴奋人体组织的过程。8字形线圈由于结构简单,常用于磁刺激中。故根据磁刺激感应电场理论,对8字形线圈改进了两种空间结构,计算其刺激深度感应电场分布,并与改进前作比较,结果表明扇形空间结构聚焦性好,更利于磁刺激兴奋点定位。更多还原

【Abstract】 The magnetic stimulation is the process that the excitable human tissue is acted with the electric field induced by the changing magnetic fields. The figure-of-eight coil was usually used in the magnetic stimulation for its simple structure.The spatial structure of the two figure-of-eight coils were improved according to the induced electric field theory.Then the distributions of the induced electric fields were studied in the stimulation depth and were compared with those of the original coils.The result indicated that the fan coil was the most effective in focusing on the fixed activating point of the magnetic stimulation.更多还原
