Calibration Procedures
Calibration procedures should be performed for quality assurance and in order to evaluate the performance of the MEG system.
CALIBRATION PROCEDURE: PERFORM WHENEVER: 1. Noise / Gain Measurement -there is line frequency noise 2. Head Coil Calibration -head localization results / accuracy is in doubt 3. EEG Gain Calibration -EEG results are uncertain 4. Magnetic Phantom Measurement -the performance of the MEG system is in question
