Active Implantable Medical Device (AIMD) safety assessments in MRI per ISO/TS 10974 may include computer simulations to evaluate radio-frequency (RF) induced heating of tissue and RF induced voltage at the device. It is not known if the differences in assessments between High-Pass (HP) and Low-Pass (LP) RF coils can be ignored. In this work, electric-fields and AIMD related RF induced heating and voltage results from HP and LP coils were compared. It was determined that there is a significant difference in safety assessment results between HP and LP coils (maximum symmetric mean absolute percentage error 50.21 ± 0.68%).
