摘要:
目的 分析癫痫脑电信号,观察癫痫患者与健康成人脑电的非线性特征参数的差异值以利于识别。方法 采用多变量相空间重构对癫痫病人的EEG进行非线性分析,通过分析得到的相关维数估算值。相关维数D2是定量刻画复杂非线性动力系统复杂性的最常用参数之一。结果和结论 相关维数能较好地识别癫痫脑电的一个特征参数。
Abstract:
Objective To study the difference between the nonlinear eigenvalue of epileptic patients and normal subjects for accurate identification of epileptic EEG signal.Methods Multivariable phase space reconstruction technique was employed to analyze the EEG of epileptic patients for estimating the correlation dimension(D2), which was one of the most often used parameters in quantitative discretion of complicated nonlinear dynamics system.Result and Conclusion The correlation dimension is an important eigenvalue for epileptic EEG identification.
