MEG Calibration Procedures

Calibration procedures should be performed for quality assurance and in order to evaluate the performance of the MEG system. Therefore whenever , when and when .

MEG Calibration Measurement consists of these procedures:
Calibration Procedure	Perform whenever:
1. Noise / Gain measurement	line frequency noise has appeared in the noise collection measurement
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
