In this work, we propose a novel 8-channel transmit and 16-channel receive constellation coil for 7T MRI. The gradient-echo images were acquired with phase shimming. The SNR was calculated and then normalized by flip angle. Transmit power to achieve 90 degree flip angle on central coronal plane was measured. Transmit and reception performance of the constellation coil were compared with that of two commercial coils that is each composed of a birdcage transmit coil and a high-density receive-only phased array. Our results show that the constellation coil can achieve excellent SNR and transmit efficiency with a single structure.
