Spacing analysis of a focal magnetic stimulating coil
Durham, NH（1997）
摘要
A promising coil geometry for focal stimulation of neurons through magnetic induction is the quad-square coil. This configuration utilizes four 90° corners at the center to produce large values of dEx /dx (considered the activating function in neural stimulation). The values of dEx/dx produced by the center of the coil are limited by the coil dimensions and coil spacing. A closed form solution of the limiting function in terms of coil dimension, spacing, and stimulating depth is presented and the relationship between dEx /dx and spacing is graphically shown
