Dipole Array was proved to be a feasible RF coil for 7T body MRI, and has the potential to meet the RF challenges at 450MHz. With Finite Difference Time Domain method, a 8-ch head dipole array was studied at 300MHz and 450MHz to explore its feasibility for head MRI at 450MHz. Results show while the |B1+| magnitude on the central transverse slice gets worse from 300MHz to 450MHz, the |B1+| uniformity does not deteriorate with frequency. Dipole is a promising RF coil candidate for 10.5T Head MRI and thus deserves further study.
