脑电图 ( EEG)中癫痫放电 ( ED s)的检出是癫痫诊断中的一个重要部分 ,当癫痫病灶位于大脑深部时 ,头皮部检测到的 ED s经常被表层的大幅度 EEG活动所掩盖。作者研究了一种非侵害性技术 ,采用用自适应聚束 ( beamformer)空间滤波器以增强可能包含ED s的大脑深部病灶的 EEG信号?
Detection of epileptic discharge (ED s) in EEG is an important part of the diagnosis of epilepsy. When the epileptic lesion is located in the deep part of the brain, ED s detected in the scalp are often overshadowed by significant EEG activity in the epidermis . The authors studied a noninvasive technique that employs an adaptive beamformer spatial filter to enhance EEG signals in deep brain lesions that may contain EDs?
