Electromagnetic field simulations and MR thermometry measurements have been used for evaluating the safety of RF coils. Increasingly, electric field measurements have been employed as an additional validation of electromagnetic field simulations, and as a means of assessing the safety of RF antennas. In this work, we investigated the application of these RF coil safety assessment techniques using a dipole antenna and "SAM" head phantom. Our results indicate that all three methods provide comparable RF safety information both in pattern and in magnitude.
