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.
