Removal of ballistocardiogram artifact from electroencephalograms exploiting heart rate variability |
Abstract | ||
|---|---|---|
An approach for eliminating the cardiac pulsation (ballistocardiogram, BCG) effect from electroencephalograms (EEG) is proposed. The artifact results from functional magnetic resonance imaging (fMRI) scanner during simultaneous EEG-fMRI recordings. The BCG artifact exhibits similar periodic physiological structure. The proposed blind source extraction (BSE) algorithm employs second order statistics to exploit the heart rate variability and focuses on the contaminated EEG segments. This method is compared with some previously developed, well-known algorithms such as FastICA, SOBI and JADE, and a qualitative comparison is given. The methods are examined for both synthetic and real data. |
