摘要

作者将基于时频信号分析的信号检测技术应用于深度脑电图记录，以检测和定位时频平面上的某些模式。本文讨论了一种特殊的模式，表示在初始阶段的放电活动。除了本文提出的固定核时频表示检测技术(Auto TFR和Cross TFR)外，还提出了一种基于信号相关的时频表示检测技术，并对结果进行了比较。

Detection and localization of complex SEEG patterns in epileptic seizures using time-frequency analysis

The authors applied signal detection techniques based on time-frequency signal analysis on depth EEG recordings in order to detect and to localize some patterns in the time-frequency plane. This paper deals with a particular pattern representing a discharge activity in the ictal phase. Beside the detection techniques using fixed-kernel Time-Frequency Representation (Auto TFR and Cross TFR) presented here, a new technique using Signal-Dependent TFR is proposed and a comparison of results is given.
