High-permittivity materials (HPM) have provided promising results in terms of higher local SNR, such as when an HPM helmet former is used in combination with a receive coil array. Since the vicinity of the coil affects the SNR and the presence of the HPM helmet prevents placement of the coil closer to the head, in this work we compare the SNR distribution when the receive array coil is mounted on top of an HPM helmet to when it is moved closer to the head. Results show that the array coil with the HPM helmet provides an overall higher SNR.
