Abstract

The radio frequency coils in magnetic resonance imaging (MRI) systems induce scattered electric fields in the implanted medical lead and result in tissue heating. A novel structure of the medical lead has been designed to reduce the scattered field. Proposed metal nails are placed along the medical lead. The scattered electric field is calculated near the medical lead tip at 64 MHz (1.5 T MRI). By installing this design on the conventional lead, a significant decrease in the scattered electric field at the tip of the lead is observed.
