With the help of the simplified electric field expressions for x, y and z gradient coils, approximate voltage values to occur on the lead are derived analytically and these values are compared with the values obtained from realistic experiments. This comparison shows that, if the path of the implant lead is known, induced voltage on the lead can be determined analytically and with the obtained result the risk of the stimulation can be examined for patients with implants prior to MRI.
