Patients with elongated conductive implants are generally excluded from MRI diagnostics because the interaction of the implant with MRI-induced RF fields can lead to hazardous localized heating in surrounding tissues. Depending on the complexity of the lead structure, numerical assessment of implant-RF interactions may require excessive computational overhead and may not be feasible. To overcome this challenge, an experimental system, based on the revised Tier 3 of the ISO/IEC TS 10974, is developed and validated with full-wave electromagnetics simulations. The experimental system is designed for the assessment of RF-induced heating of implants, irrespective of the complexity of the implant structure.
