The RF coils in Magnetic Resonance Imaging (MRI) systems induce scattered electric field in the medical implant, and the principal bio effect is tissue heating. In this work, a noble design to reduce the scattered field has been proposed. In this proposed design, metal nails have been placed along the length of the medical lead. The scattered electric field is calculated near the lead tip at 64 MHz for a model implant by using Ansoft HFSS. By using this method, a significant decrease in the scattered electric field has been observed.
