Abstract

A computationally practical method for performing moving dipole calculations to localize EEG sources in realistic, boundary element (integral equation) type of head models is presented. This method makes use of a rapid method of solving the forward problem of calculating the EEG's produced by a dipole in a realistic head model. This rapid forward calculation method allows the use of standard Simplex search techniques to solve the inverse problem of localizing electrical sources in the brain from EEG's measured on the scalp.

摘要

提出了一种计算上可行的方法，用于在逼真的边界元（积分方程）类型头部模型中执行移动偶极子计算以定位脑电图源。该方法利用了一种快速方法来解决在逼真的头部模型中计算偶极子产生的脑电图的正向问题。这种快速正向计算方法允许使用标准单纯形搜索技术来解决从头皮上测量的脑电图定位大脑中电源的逆问题。
