A 32-channel receive coil with variable-density element distribution, in conjunction with an 8-channel transmit coil, was developed for imaging of the occipital-parietal regions of human brain at 7T. Spatial SNR maps demonstrate targeted sensitivity to the peripheral occipital pole, with a smoothly varying SNR proximal to this region. The temporal SNR of the occipital-parietal coil attained 35% higher SNR in the visual cortex than a whole-head coil.
