Keywords: Safety, Safety, Heating, RF-Induced Heating, MRI Safety Evaluations, SimulationASTM F2182 was developed to evaluate RF-induced heating near passive implanted medical devices by subjecting an implant within an average tissue-mimicking (i.e., electrical and thermal properties) phantom to controlled RF exposure. The purpose of this study was to determine if the ASTM F2182 phantom is adequate for determining worst-case RF-induced heating of implanted medical devices. Results from this study display that device temperature rises in the ASTM F2182 are significantly higher than in-vivo temperature rises, regardless of tissue-specific properties and local blood perfusion incorporation to the phantom, indicating that the ASTM gel phantom is adequate for RF-induced heating evaluations.
