Quantitative patient-specific local SAR estimation is highly desired in UHF MRI applications. In this work, using a 16-channel transceiver head coil at 7T, based on previously proposed method, we report our simulation study from single element complex B1 mapping to in-vivo local SAR estimation on a realistic geometry head model. Promising simulation results suggest its feasibility and reliability. Establishment of real-time EPT technique may have a significant impact on patient-specific SAR management in parallel transmission at UHF.
