Patients with deep brain stimulation (DBS) implants significantly benefit from MRI, however their access is restricted in these patients because of safety concerns due to RF heating of the leads. Recently we introduced a patient-adjustable reconfigurable MRI coil system that significantly reduced the SAR at the tip of single DBS leads (unilateral) in simulation studies during MRI at 1.5T. Here we present the first in-vitro measurements of RF heating-reduction performance of the coil system showing a significant reduction in heating of realistic bilateral DBS implants.
