Abstract :
Electromagnetic interaction between a radio frequency surface coil for magnetic resonance imaging (MRI) and a heterogeneous human model implanted with a pacemaker system has been studied in order to provide safety requirements and to estimate potential damaging of the device. Since the coil can be considered an electrically small structure, an equivalent model has been considered and validated in order to reduce calculation burden in time domain simulation by using a Finite Integration Technique (FIT).
