Abstract
The effect of skin tissue on the scattering of the MRI RF field by deep brain stimulation (DBS) leads is analyzed. RF induced heating occurs in the tissue surrounding the electrodes at the end of such a medical lead. The electric field and the induced temperature rise are found by solving the wave and heat equations. Spatial plots of the solutions are obtained. The presence of skin tissue also affects the transmission line behavior of the lead, and the resonant length; these effects are discussed.
