An on-line system for intraoperative focus localization from array electrocorticography
A system for the intraoperative localization of the focus of epilepsy from array electrocorticography is presented. The spatio-temporal structure that characterizes the surface potential field during the occurrence of focal interictal events is discussed. The spatio-temporal Laplacian transformation is proposed for selectively emphasizing these occurrences. The implementation of the online localization system in a multiprocessor platform is outlined and detailed results from three surgery cases are shown.<>
