MEG Calibration Procedures

Calibration procedures should be performed for quality assurance and in order to evaluate the performance of the MEG system, whenever line frequency noise has appeared in the noise collection measurement, when head localization results / accuracy is in doubt and when EEG results are in doubt.

MEG calibration measurement consists of these procedures: 1. Noise / Gain measurement, 2. Head coil calibration, 3. Magnetic phantom measurement and 4. EEG calibration.
