Using numerical simulations, we explore the potential of
a single high-permittivity receive head coil former to
improve performance of a large encircling transmit array
at 7T for six different human subjects with a wide range
in size and morphology. This is important to demonstrate
the possibility of incorporating HPMs into arrays for
high-throughput, high performance MRI. The ability to
perform RF shimming with the large volume array was not
adversely affected by the presence of the
high-dielectric former in any of the subjects and the
former greatly improved efficiency and homogeneity of
the transmit array for all subjects.
