We measured temperature increase (ΔT) in anesthetized swine using fluoroscopic probes and compared our results to the simulated solutions obtained from digital models of the same swine. For our studies, we used a 4 channel fractionated dipole array that is placed on the neck/upper back region. Electromagnetic and thermal simulations were performed along with in vivo experiments with different RF excitation patterns at 10.5 T.
