A Quadraure RF Coil with Reduced Heating of DBS Implants

DBS implant heating inside MRI scanner is a major safety concern for scanning implant patients. In order to prevent catastrophic ablations of surrounding tissues, current approaches include using head-only transceiver coils with much reduced SAR limits or redesigned lead wires with RF chocks. Such procedures prevent many clinical useful protocols that are based on the spin-echo sequence from being applied, and exclude patients with different types of implant leads from being scanned. The aim of this study is to develop a new RF transmitter based on the transverse electromagnetic mode of parallel-plate waveguide.
