A novel coil element and array geometry is explored for a 1.5Tesla, 16 channel phased array knee application. The coil element, resembling a bell, exhibits a marked improvement in center-of-view SNR (12% relative to standard rectangle), while simultaneously giving a rapid drop off in sensitivity outside of the periphery, thus reducing artifact occurrence. We examine the optimization of array geometry, and demonstrate the performance of the proposed array through phantom experimental studies, as well as simulation design.
