Abstract
During a Magnetic Resonance sequence, simultaneously acquired ElectroEnceph aloGraphy (EEG) data are compromised by severe pollution due to artifacts o riginating from the switching of the magnetic field gradients. In this work , it is shown how these artifacts can be strongly reduced or even removed t hrough application of an adaptive artifact restoration scheme. The method h as proved to be fully automatic and to retain high frequency EEG informatio n, which is indispensable for many EEG applications. (C) 1999 Elsevier Scie nce Inc.
