The function of human cerebellum is underexplored in vivo, due to its small size and its placement at the bottom of the brain where transmit fields are suboptimal at 7Tesla. Here, we combined 2 dense coil arrays of 16 small surface receive elements each with a transmit array of 3 antennas elements. Our results show improved B1+ and SNR close to the surface as well as g-factor gains compared to a whole-head commercial coil. This resulted in large gains in the surface (< 3.5cm) in the spatial extent of the BOLD activation, at the cost of increased signal inhomogeneity.
