Abstract

A standard EEG equipment was modified in order to work properly during ultra-fast MRI acquisitions. Changes include: amagnetic electrode cap, optical fiber link, shielding box for EEG amplifier, twisted low metal mass cable. The effects of the RF pulse and time varying magnetic fields were minimized by using a correct head cap wires locked environment montage and then removed with a simple subtraction algorithm during EEG/fMRI acquisition. Ballistocardiogram artifact was also minimized at suitable levels by using a comfortable head position and immobilization.
