基于球諧分析的腦電圖映射成象方法
IMAGING OF EEG BY SPHERICAL HARMONIC ANALYSIS
-
摘要: 本文提出用球諧分析完成腦電信號內(nèi)向延拓,進(jìn)而實(shí)現(xiàn)腦電圖三維映射成象的方法。文中介紹了方法原理,并進(jìn)行了計(jì)算機(jī)仿真試驗(yàn)研究。仿真效果證明了方法的有效性和可行性。

Abstract: A new three dimensional imaging method for electroencephalogram (EEG) is suggested. It consists of the solution of an inward spherical harmonic continuation. After introducing the principle of the new method, numerical simulation is made and the feasibility of the method is confirmed by the simulation results. -
