Lead heating and malfunction of implantable medical devices, such as Spinal Cord or Deep Brain Stimulators, due to MRI RF field exposure are patient safety concerns. The transfer function is a method used to calculate predictions of MRI-induced heating or injection voltages. This study investigated the repeatability of a measurement-based transfer function system. Results showed that the inherent variation of the system can be minimal, whereas lead positioning in the system has a higher impact on variation.
