A 128-channel receive array has been designed and prototyped for human head imaging at 10.5T. The coil employs miniaturized electronics and flexible PCB laminates for loop conductors. Bench measurements and MR experimental results for an 8-channel cluster of loops are presented which show low coil coupling and good stability during echo-planar imaging. Electromagnetic simulations will provide an estimate for the SNR gain that can be expected from this 128-channel receive array over a 64-channel receive array tuned to the same frequency. This simulation estimate will be verified with experimental results which will include intrinsic SNR and g-factor maps.
