This application note is concerned with the implementation of subject electrical stimulation in the fMRI and MRI for the purposes of psychophysiological research. The setup presented physically limits the stimulation energy to be less than 300mJ under all operating conditions and restricts the electrical stimulation pulse widths to be 2ms or less. The setup only supports fully programmable, voltage-controlled, voltage stimulation.
