At high field strength, safety assessment of local
multi-channel arrays currently relies on electromagnetic
field simulations. Additional verifications of the
accuracy of the simulated RF array can be performed
using E-field or temperature measurements with
additional probes, or with B1+ measurements. In this
work, we investigated the use of MR thermometry as a
validation tool of the representation of the RF array in
simulations. Our results suggest that MR thermometry is
a valuable tool readily available in any MR scanner for
transmit array safety assessment
