Here we report the numerical calculation results for the B1 field and SAR evaluation in a 3T neonate head coil containing an anatomically-accurate head model using the finite difference time domain (FDTD) method. The FDTD model of the coil was created directly from CAD models of the actual coil, and features an end cap, four-port drive, asymmetric end ring, and slightly larger spacing of anterior-most elements to allow for ventilation/monitoring equipment. Maximum time-average dissipated power to avoid exceeding limits on local and average SAR are presented.
