Quality Assurance

MEG 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. Magnetic Phantom Measurement -the performance of the MEG system is in question
4. EEG Calibration -EEG results are uncertain
