脑电计算问题应用平台的设计与实现

Design and implementation of the application platform for calculation of EEG problem

脑电正及脑电逆问题的研究一直是脑电研究领域的核心。文中针对脑电计算问题进行了算法研究和软件系统设计开发。首先对已有的脑电计算方法进行研究分析,选出适宜的计算方法嵌入到软件系统中;基于Visual C++6.0平台,设计开发了系统软件,脑电正系统可以以灰度图形式直观显示出脑电压大小的分布情况,脑电逆系统可由获取的脑电数据快速地计算出偶极子电偶极矩的大小并实时显示。该系统具有界面友好、操作简单、易于扩展等特点。

There are two research focuses in the field of EEG, forward problem and inverse problem. This paper presents the research for choosing the optimal algorithms and designing the software system based on the chosen algorithms, designs and implements of software system based on the Visual C ＋ ＋ 6.0 platform. The forward system shows the distribution of the voltage with grayscale. Similarly, the inverse system shows the strengths of the dipoles real-timely. The system has characteristic of friendl interface, easy operation, software extensibility.
