This engineering/simulation study evaluates RF applicator array designs for Thermal Magnetic Resonance (ThermalMR), which combines MRI with RF hyperthermia for brain tumor theranostics. Using EMF and temperature simulations at 7.0 T, 9.4 T, and 10.5 T, hybrid loop+SGBT dipole arrays are reported to provide superior…
