局灶性癫痫侵入性脑电图的重整熵定量分析
Quantitative analysis by renormalized entropy of invasive electroencephalograph recordings in focal epilepsy
摘要：
应用重整熵方法分析了10例局灶性癫痫患者的有创脑电图（EEG）。作为一个复杂的措施，不同的制度的动力系统，功能测试在癫痫发作的时空行为。在所有患者中，发现在癫痫发作期内重整化熵降低，而且这种降低的强度与记录位置到病灶的距离单调相关。结果表明，重整化熵的方法是一个有用的程序，临床应用，如癫痫发作的检测和定位的癫痫灶。
英文摘要：
Invasive electroencephalograph (EEG) recordings of ten patients suffering from focal epilepsy were analyzed using the method of renormalized entropy. Introduced as a complexity measure for the different regimes of a dynamical system, the feature was tested here for its spatio-temporal behavior in epileptic seizures. In all patients a decrease of renormalized entropy within the ictal phase of seizure was found. Furthermore, the strength of this decrease is monotonically related to the distance of the recording location to the focus. The results suggest that the method of renormalized entropy is a useful procedure for clinical applications like seizure detection and localization of epileptic foci.
