A 12-channel dorsal receive-only array was built for use with an 8-channel transmit/ receive coil. The 12 elements were geometrically decoupled. The array was evaluated through measurements with a vegetable oil phantom and a volunteer. The g-factor was calculated from the SNR of the images using the pseudo multiple replica method. Maps of the g-factor using only the 8-channel transmit/ receive body coil were compared to those obtained using both the 8-channel coil and the 12-channel array. As expected, the parallel imaging capability was enhanced by the 12-channel array.
