In this work, we propose an approach to construct the 20-channel head/neck coil with extended longitude coverage and high SNR by combining a commercial 12-channel head array and adedicated 8-channel carotid array in convenient fashion. The coupling effects are compensated by accounting for the noise correlation matrix in the reconstruction method. Both phantom and in-vivo experiment results show that the proposed array is capable to provide a large coverage from carotid to brain vessels with high SNR and good parallel imaging performance, which will benefit arterial disease diagnosis.
