【摘要】：经颅磁刺激技术的推广普及一直受限于其定位精度上的不足,作为一种依靠硬件设备来实现功能的技术手段,其定位精度与诸多因素有关。从硬件优化方法和定位基础理论两方面,阐述这一领域的研究进展。通过对圆线圈、8字形线圈、Slinky线圈、H-线圈以及双锥线圈这5类不同线圈的定位特点进行分析比较,以及对常规导航系统的定位效果进行简要说明,揭示定位基础理论对于硬件操作指导的重要性。基于目前定位技术的难点和定位研究的热点,指出未来的发展研究方向:即通过构建高空间分辨率的刺激导航系统,并结合医学成像技术,在消除个体差异性的结构尺度上寻求TMS磁刺激的微观作用机理,以此推导出定位问题的一般性解决办法。
[Abstract]:The popularization of transcranial magnetic stimulation (TMS) technology has been limited by its lack of positioning accuracy. The positioning accuracy is related to many factors. This paper describes the research progress in this field. Through the analysis and comparison of the localization characteristics of five different types of coils, the circular coil, the zigzag coil, the Slinky coil and the double conical coil, the localization effect of the conventional navigation system is briefly explained. This paper reveals the importance of the basic positioning theory for the guidance of hardware operation. Based on the difficulties of the current positioning technology and the hot spot of the localization research, this paper points out the research direction in the future: that is, by constructing the stimulating navigation system with high spatial resolution, Combined with medical imaging technology, the microcosmic mechanism of TMS magnetic stimulation is sought on the scale of eliminating individual differences, and the general solution to the localization problem is deduced.
