EEG MR Correction - for detecting and correcting MR scanner artifacts

The MR Correction transform allows the detection and correction of artifacts that occur during

combined EEG-fMRI measurements in an MR scanner as a result of changes to the magnetic

field in the scanner. The basic principle behind the correction of scanner artifacts is that the

intervals interfered with by the MR scanner are averaged. This approach reduces the proportional

contribution of the EEG to the averaged curve because the EEG sequences are statistically

independent of one another. This results in a correction template which contains only a small EEG

contribution and which replicates the scanner artifact.
