Geodesic EEG System MR for EEG-MR and EEG-MEG Research

Dense array EEG-fMRIEGI’s magnetic resonance imaging (MRI) compatible EEG system is the first practical whole head EEG product that works within the MR or MEG environment.

Simultaneous EEG-MR multimodal imaging combines MRI’s high spatial resolution and EEG’s high temporal resolution to record brain activity more completely. Read more about spatial and temporal resolution of fMRI and dEEG.

EGI's MR-compatible EEG Systems can also be used for simultaneous EEG-MEG multimodal imaging.

System Features

  • Versatility. Use your GES MR in the MR environment or in the lab. There is no need for separate systems.
  • Reduced noise. The Field Isolation Containment System (FICS) features shielding and input filtering that significantly reduce the effect of noise sources in the MR environment.
  • Channel counts. EGI’s fMRI compatible EEG systems are available with 32, 64, 128, or 256 channels.
  • Upgradeable channel counts. The GES MR is upgradeable by channel count so you can work with the full power of dense array EEG when you are ready.
