“…RF-induced currents on elongated implants depend on the magnitude, polarization, and phase distribution of MRI incident electric field along the length of the implant (19)(20)(21)(22)(23)(24). This means that the trajectory and position of an implanted lead has a decisive effect on the magnitude of RF heating around its tip (13,(24)(25)(26). For this reason, a robust and reliable RF safety evaluation should include realistic patient-derived device configurations.…”

“…It is established that the trajectory of an elongated lead and its position within the MRI coil strongly affects its RF heating [24][25][26][27][28][29][30]. The extracranial DBS lead trajectories (i.e., the trajectory of the portion of the lead that is outside of the brain and placed over the skull) vary substantially from patient to patient, depending on the surgeon's practice styles.…”

“…A wide literature is available for active implantable medical devices (AIMDs), as the concern of scanning these devices has emerged earlier. For instance, some studies show how the pacemaker lead trajectory can significantly modify the amount of heating (Nordbeck et al 2009, Mattei et al 2008, 2010, Yao et al 2021, Nguyen et al 2022. Similar analyses were performed on Deep Brain Stimulation (DBS) devices, analysing the role of lead configuration (Golestanirad et al 2017, McElcheran et al 2019, the accurate modelling of the electrodes (Guerin et al 2018), body's composition and the tissue around electrodes (Iacono et al 2013, Bhusal et al 2021 and the way to reduce the heating (McElcheran et al 2015).…”
