Novel RF coil designs must address ultra high field MRI challenges and simultaneously exploit benefits thereof in terms of higher signal-to-noise ratio and reduced acquisition time. A 15-channel RF array was built composed of a 7-channel loop receive array and an 8-channel dipole transceiver array with the receive array designed to be scalable to high density arrays. Transmit B1 maps demonstrated transmit field immunity to receive array insertion. The absolute SNR generated by the loop array receiver is on average 2.65 times the absolute SNR of the dipole transceiver in locations near the receiver array. The coil was successfully used in combination with dipole transceivers to acquire in-vivo swine brain anatomical images at 10.5T.
