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.
