Abstract :
Variability of the tissue in which implant is embedded and the length of the bare part of the implants were studied with regard to MRI-related heating. The implants studied were thin and elongated with different effective resonant lengths. We compare two leads having different lengths of bare portions to investigate the heating effect. To support our conclusions, we compare the leads based on current distributions, SAR distributions, and their associated temperature rises in the tissue.
