脑电地形图分析系统

AN EEG TOPOGRPHIC SYSTEM

本文介绍了一个以微型计算机为工具,根据频谱分析原理,对大脑自发性和节律性电信号进行处理,将处理结果直观地显示在头脑模式上的脑电功率谱地形图分析系统。该系统在脑电图机的基础上扩展而成。初步临床实验表明,系统性能良好,是医生诊断大脑疾病的一个重要辅助工具。

An analytical system, employing a micro-computer, for topographic dawing of EEG power spectra is introduced in this paper. The spontareous and rhythmical signals of the brain are abtained from the normal EEG multichannel recorder and analysed by the system based on FFT. The results are drawn in the head model. From the clinical applications to the diagnosis of brain illneses, this system is very helpful to the docters.
