A loop coil with a highly non-uniform current
distribution can capture loop like and dipole like
fields. This loopole element provides the opportunity
to tailor both the orientation and the intensity of its
asymmetric current to achieve improved B1+ efficiency or
SNR. In this work the feasibility of using loopole
elements as building blocks to create transceiver arrays
is explored. A novel split four-element loopole array
with two anterior and two posterior elements was modeled
and constructed. The array was used to image the human
spine at 7.0T. The loopole array exhibited substantial
performance improvements over published spine array
designs.
