分析处理脑电波信息是一个比较复杂的问题,国外多用小型机或专用机完成。本文介绍一个使用八位微型计算机实现的处理系统。它在对波形进行频谱分析的基础上,将处理结果综合在一起以地形图(TOPOGRAPHIC MAPPING)显示,直观地报告病变部位。该系统除对单接法采样数据进行处理外,还建立了对双接法和三角定位的处理,临床使用取得良好效果。文中结合实际问题对如何处理大量信息数据和提高处理速度等方面作了详细论述。
Analysis and processing of brain waves information is a more complicated issue, foreign miniseries or special machines to complete. This article describes a processing system implemented using an eight-bit microcomputer. Based on the spectrum analysis of the waveform, it combines the results of the treatment with TOPOGRAPHIC MAPPING to visually report the lesion. The system in addition to single-sample data processing, but also established a double-junction method and the triangular positioning of the treatment, clinical use achieved good results. In this paper, a detailed discussion on how to deal with a large amount of information and data and improve the processing speed is given in detail in the light of practical problems.
