Source Region Contracting Method for EEG Source Reconstructions

摘要

A new EEG source reconstruction method is presented. The method reduces the number of unknown quantities of the basic EEG equation by contracting the source region iteratively. The equation system turns from an underdetermined system to an ovcrdetermined system step by step. At last the least square algorithm is used to get a unique solution. The simulation shows that a high-resolution result can be obtained by using the method proposed.
