The patented* MagLink system is used for obtaining integrated EEG and ERP recordings inside the fMRI. This second-
The gradient artifact that is injected into the EEG data can be reduced by a number of different strategies that are included in the CURRY 7 software. Having a variety of data processing methods available is critical to account for the different artifacts that are encountered. The individual artifact signatures vary based on the type of pulse sequence, magnet type and strength, the electrode impedance, even the quality of the shim on a particular day. Neuroscan's correction methods can correct the EEG data under a variety of parameters.
The most recent development affecting gradient artifact reduction derives from the ability to synchronize the clocks between the amplifiers and the MRI Scanner. Clock synchronization improves the accuracy of gradient artifact reduction, simplifies the artifact reduction process and allows acquisition using standard sampling rates (e.g., 500 Hz).
The complete MagLink system consists of MagLink Cables, MagLink Caps, a Neuroscan amplifier and the CURRY 7 software. This fully functional system has acquired EEG and fMRI data successful in the following magnets:
