Inspired by recent theoretical work indicating that z-oriented currents could capture most of the optimal SNR and outperform loops in reception at high frequencies, we constructed and evaluated a close-fitting dense dipole receive-only head array with 29 elements. The array was combined with a dual-channel transmit birdcage for experiments. SNR was good throughout a head phantom at 7T and outperformed a commercial head coil in regions above and below the center. Future work will focus on detuning mechanisms for dipole elements to enable safe in-vivo measurements.
