Motivation: Evaluate the impact of EPI read-out gradient slew-rate on EEG amp heating, for EEG-fMRI experiments at 7T.
Goal(s): Identify slew-rates that will minimize heating of EEG amps, for EEG-fMRI experiments at 7T.
Approach: Test a range of EPI slew-rates while measuring the temperature of the EEG amp, during phantom tests at 7T.
Results: EPI read-out slew-rates of 120, 88, 61 and 46 T/m/s were tested and the slew-rates of 61 and 46 T/m/s were found to induce minimal heating of the EEG amp during EEG-fMRI experiments at 7T.
Impact: These results should help neuroscientists doing EEG-fMRI studies at 7T, to conduct their experiments without damaging the EEG amps.
