The coverage of receive coil array is an important concern in coil design especially for monkey head coil. The simulation of receive coil array is helpful in decision-making. For macaque brain imaging at 7T, five coil array configurations with different coil coverage under realistic considerations were systematically evaluated through quantifying their spatial SNR profiles and parallel imaging acceleration performance. Extending the traditional helmet coverage design for monkey head to whole-head coverage demonstrated substantial improvement in acceleration performance in deep brain region, but less pronounced enhancement can be observed in spatial SNR profiles in brain area.
