An 8-element anterior array based on central 3-elements Y-shape arrangement was combined with a rectilinear 8-elements posterior array to form a dedicated 8Tx/16Rx pTx transceiver cardiac array for pigs was developed. The hardware and imaging performance of the pig array was validated through EM-simulations, phantom and ex-vivo MR-measurements at 7T. Combined SNR, FA, g-factor maps, and high-resolution ex-vivo cardiac images were acquired with an in-plane resolution of 0.3mm×0.3mm. A SNR of 36±23 was achieved within the heart of the pig. Parallel imaging with acceleration factor (R=4) was possible while keeping the mean g-factor within the heart region at 1.14.
