Preface
elcome to the MR-conditional Geodesic EEG System™ 400 MR
(GES MR) Series systems from Electrical Geodesics, Inc. (EGI).
GES MR systems work within the magnetic resonance (MR)
environment to allow the simultaneous acquisition of electroenceph-
alographic (EEG) and functional magnetic resonance imaging (fMRI)
data. The components of GES MR systems, including the HydroCel
Geodesic Sensor Nets™ (HC GSNs, or Nets) and the Net Amps™ (NA)
amplifiers, have been specifically designed to significantly reduce the
EEG and MRI systems’ impact on each other by minimizing and
attenuating contrary signals and artifacts.
CAUTION: Only MR-trained personnel should work with this
equipment and only equipment labeled MR safe or MR conditional
should enter the specified MR environment. Adhere to all precautions
given in the “Safety and Use Conditions” chapter.
For all safety and use conditions for using the GES system outside of the MR
environment, refer to the GES 400 series manual (8100400).
