Keywords: Interventional Devices, MR-Guided Interventions, Thermal MRThis work proposes the concept of four RF applicators combining SGBT dipole and loop building block antenna array for diagnostic proton (1H) imaging and thermal intervention at 7.0T, 9.4T and 10.5T. We demonstrated the relationship between spatial arrangement of the antennas in RF applicator and the SAR profile which further related to temperature rise for targeted thermal intervention of deep-seated brain tumors. This approach of design, simulation, optimization of EM power deposition followed by calculation of the resulting temperature distribution can be adapted as a pre-routine to conduct optimization result for individual patient for further treatment planning.
