Simulation of B1+ efficiency (a and b), 10 g SAR (c and d) and SAR efficiency (e and f) maps of the 16-channel dipole and the 16-channel asymmetric sleeve antenna arrays with a human head model (Duke) in an axial, coronal, and sagittal planes. The peak 10 g SAR of the 16-channel asymmetric sleeve antenna array (d) is substantially lower compared to the 16-channel dipole antenna array (c). SAR efficiency of the 16-channel asymmetric sleeve antenna array (f) is higher compared to the 16-channel dipole antenna array (e).
