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.
