EGI Dense Array EEG System tested in 7T MRI machines

27 Apr 2016 – EGI has recently tested the Geodesic EEG System (GES) 400 MR amplifier in a Siemen’s 7T Magnetom MR scanner. Based on the data reviewed, EGI's risk management team has come to the conclusion that the GES 400 MR poses no known hazards at this time when used in a Siemens 7T MRI environment. The Physio16 MR input box is still being tested.

Based on the results of the tests with the GES 400 MR amplifier and the 256 MR HydroCel Geodesic Sensor Net products, it is probable that the GES 400 series and the 256­ channel HydroCel Geodesic Sensor Net MR products will perform without hazards due to deflection, torque, or RF induced heating with other 7T systems. However, we suggest that anyone wishing to the use EGI’s GES 400 MR system in a 7T MRI system from a different manufacturer perform safety tests.

Contact EGI for the document “7 Tesla torque and displacement safety tests report” for further details.
