Glioblastoma multiforme is the most frequent and most aggressive malignant brain tumor with de facto no prognosis of long-term survival by the use of current multimodal therapeutic approaches. RF heating at ultrahigh fields (B0=7.0T, f=298MHz) has the potential of delivering sufficiently large thermal dosage for hyperthermia of relatively large tumor areas. This work focuses on EMF simulations and compares RF applicator designs tailored for simultaneous RF heating and MRI. Our results suggest that RF power can be focused to small tumor areas and to large clinical target volumes derived from segmented patient data.
