In order to tailor to two-dimensionally accelerated parallel MRI in 3D brain imaging, we develop a 32-channel head coil array with circularly symmetric geometry at 3T. Specifically, 32 curved trapezoidal RF coils were arranged evenly to cover the whole brain. RF coils are decoupled by overlapping and low-noise preamplifiers. The mechanical housing of the array was designed to ensure easy access. Preliminary structural images show good sensitivity and SNR over the whole brain. Nine-fold accelerated structure image (3x3) shows good white/gray matter contrast.
