We propose a method mitigated the radiofrequency heating at the
contacts of a DBS electrode by utilizing an implant-friendly excitation scenario
at 7T. The proposed approach is able to successfully mitigate the shaft
current and RF heating at the contacts.

inside the indicated ROI using the scanner’s shimming toolbox vs. the IF modes.
Turbo spin-echo images were acquired, and the electrode’s tip temperatures were
measured for both shimming scenarios.
