Achievable gradient performance scales with decreasing gradient size which awakes interest in tight-fitting gradient coil design and requires space-restricted RF solutions. In this work, an eight-channel transmit-receive array coil for human head with a B1 field distribution preventing aliasing from the unambiguity volume of a high performance gradient insert and assuring a low eddy current capability is presented. In this configuration, acceptable homogeneous excitation and parallel imaging can be performed even despite the limited space for RF components.
