In this work we provide complete 3D predictions of the B1+ fields, MRI images, energy absorption by the head and corresponding specific absorption rate (SAR) distributions, temperature rise distributions over the whole head for MRI experiments associated with quadrature and multi-transmit (B1 shimming) operations at 7 tesla.. Analysis on the relation between B1+ field distributions, MR images, SAR and T (temperature change due to the RF excitation) distributions is conducted.
