A novel combined shielded-loop-resonator (SLR) and dipole antenna 16-channel transceiver body imaging array (16-SLR-D) is designed by combining eight pairs of dipole antennae and 10x20cm2 SLRs. Performance of the 16-SLR-D is compared against a 16-channel loop-dipole (16-L-D) array through finite-difference-time-domain simulations. Despite the larger loops size and closer placement of the elements, 16-SLR-D design has significantly improved coupling performance with less than 6% power coupled to other channels on average, compared to ~16% of average power coupling of 16-L-D. The combined SLR-dipole array(16-SLR-D) demonstrated ~+15% in transmit efficiency(mT/W0.5), ~+9% in transmit SAR efficiency (mT/SAR0.5) and ~+6% SNR inside the prostate.
