We developed a 16-channel transceiver body array (16LD) by combining loop and dipole elements, and compared performance against 16-channel microstrip-line (16ML) and 10-channel fractionated dipole antenna (10DA) arrays. Complementary field characteristics of loop and dipole elements were utilized by symmetrically placing them along their long-axes. The loop-dipole combination allowed increased channel counts and density while limiting inter-element coupling. The 16LD had improved transmit and receive performance over the 16ML and 10DA in both simulations and experiments. Images of the prostate, kidneys and heart were acquired showing the potential of the 16LD to successfully image targets throughout the body at 7.0T.
