A method for validation of the simulation model with respect to experimental results is introduced for an 8-channel parallel-transmit dipole coil array. An original approach to include RF losses is described. The simulation results were quantitatively compared to the experimental data in terms of scattering parameters, individual transmit field (magnitude/phase) and combined transmit field. Two distinct configurations, not including RF losses were compared to the proposed approach. High correlation was achieved between simulated and experimental data. We conclude that with the proposed approach for RF losses, a robust validation is achieved for the 8-channel parallel-transmit dipole coil array at 7T.
