Electroencephalographic source reconstruction by the finite-element approximation of the elliptic Cauchy problem.
IEEE Transactions on Biomedical Engineering(2021)
Abstract
Objective: This paper develops a novel approach for fast and reliable reconstruction of EEG sources in MRI-based head models. Methods: The inverse EEG problem is reduced to the Cauchy problem for an elliptic partial-derivative equation. The problem is transformed into a regularized minimax problem, which is directly approximated in a finite-element space. The resulting numerical method is efficien...
