To improving the SNR and the g-factor in a vertical-field MRI, a multi-channel head coil has been developed. The coil consists of loop/dipole parallel RF coils (LDP) that improve the signal detection efficiency in the deep region of the subject in the vertical-field MRI. The performance of the coil was evaluated in a phantom experiment at 1.2T vertical-field MRI. The SNR and the g-factor of the coil using LDP were 1.2 and 1.2-2.9 times better than those of a conventional head coil, respectively. This technique will contribute to improve the performance of the vertical-field MRI.
