High permittivity dielectric pads are known to be effective for tailoring the RF field and improving image quality in high field MRI systems. Despite the number of studies reporting benign SAR effects, their safety remains a concern and should be evaluated on an application-specific basis using RF simulations. In this work we demonstrate the impact of insulation material on the RF safety of high permittivity pads, using both RF simulations as well as phantom experiments.
