Local Specific Absorption Rate (SAR) is a major problem for high field MRI, particularly when using multiple transmit channels. In this study, a patient-specific estimation of local SAR based on B1 mapping is presented. Experimental results imaging healthy volunteers are validated using subject-specific FDTD simulations. It is found, that the presented approach yields a sufficiently accurate and patient-specific local SAR measurement.
