摘要:
在探讨EIT技术工作原理的基础上,进行了大脑受到外界刺激反应的非侵入实验的实验方法研究及实验方案论证,根据大脑分别接受外界听觉和视觉刺激时所记录的实验数据,得出了不同电极对电流驱动情况下参考数据的变化曲线,听觉和视觉的EIT数据对应于参考数据的变化曲线,以及同一个测试对象在不同刺激(听觉和视觉)时的EIT电压变化曲线。通过对所得到的曲线进行比较、分析,发现了两种不同外界刺激下大脑电参数变化所引起的EIT电压变化的规律,为进一步实现EIT图像重构,分析大脑的活动规律奠定基础。
Abstract:
On the basis of investigating fundamental principle of EIT ( Electrical impedance tomo- graphy) technology, themethod and the setup of noninvasive experimental study of hum an brain due to external stimuli are discussed. According to the EIT data collected due to auditory and visual stimuli respectively, the curves of reference data changesunder different current drives, the auditory and visual EIT data versus reference data and the curve ofEIT voltage changes due to two different stimuli of the sam e subject are obtained. Through comparison and analysis, the rule of EIT voltage changes of human brain due to two different stimuli is revealed and the result helps to analyse the ac- tivity of brain and to reconstruct the EIT image.
