Artifacts are removed from EEG signals by segmenting EEG data that are continuously recorded during an MR scan with respect to a time period based on the MR scan, thereby obtaining n temporally consecutive segments of EEG data. For each segment j of the n segments, it is determined whether movement is detected when the segment j is recorded. In the case of no movement, the segment j is selected for a template k. In case movement is detected, EEG data of segments of the n temporally consecutive segments which have been selected for the template k are averaged, thereby obtaining the template k, the template k is subtracted from the EEG data of the segments, k is incremented, and the segment j is selected for the template k. In case no movement is detected and j=n, the segment j is selected for the template k and EEG data of segments of the n temporally consecutive segments which have been selected for the template k are averaged, thereby obtaining the template k, and the template k is subtracted from the EEG data of the segments. |
