Recently we presented the feasibility study of using a reconfigurable DBS-friendly head coil, composed of a patient-adjustable rotating birdcage transmitter, and an integrated 32-channel receiver array to reduce SAR during imaging of patients with deep brain stimulation implants. Here we introduce the first prototype of such coil system, and present results of finite element simulations on patient-derived numerical models of realistic DBS lead trajectories, which characterize its SAR reduction performance.
