We present a coil array for neuroimaging at 9.4T which is capable of accelerated excitation and reception in all three directions. It employs sixteen receive elements while two coils are combined during transmission due to the limited number of independent transmitter channels. The array has been approved for application in a clinical trial and first in vivo experiments demonstrate its imaging capabilities.
