Assessment of local RF-induced heating of AIMDs during MR exposure

Patients with active implantable medical devices (AIMDs) are generally excluded from magnetic resonance imaging (MRI) diagnostics because the interaction of the AIMD with MRI-induced radiofrequency (RF) electromagnetic fields (EMFs) can lead to hazardous localized heating in surrounding tissues. In this work, two safety assessment methods, based on Tiers 3 and 4 of the Technical Specification ISO/IEC 10974, for a generic AIMD, for which a cardio application is assumed, are implemented, and the results from the assessments are illustrated.
