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.
