To increase the SNR of an RF array coil for vertical field MRI, a loop/dipole parallel RF (LDP) coil was developed. The SNR was increased by forming a solenoid shaped current on an array coil using the LDP coils. The performance of the coils was evaluated using an electromagnetic simulator. The SNR of the LDP coil was 9% better than that of a conventional loop array coil. This technique will contribute to increasing the SNR of the array coil for vertical field MRI.
