In this paper we evaluate through simulations the SNR improvement in the head when a high-permittivity helmet former is used with a 28 channel receive array coil. The impact on the SNR of parallel imaging applications is also considered. An overall improvement in the brain is observed when the high-permittivity helmet is used with an average SNR increase of about 51%, and a maximum improvement of 220% in a location on the side of the head. During parallel imaging applications a significant improvement can be still observed in presence of the high-permittivity helmet, but some SNR reduction is observed in the head when high acceleration factors are performed.

Abstract
In this paper we evaluate through simulations the SNR improvement in the head when a high-permittivity helmet former is used with a 28 channel receive array coil. The impact on the SNR of parallel imaging applications is also considered. An overall improvement in the brain is observed when the high-permittivity helmet is used with an average SNR increase of about 51%, and a maximum improvement of 220% in a location on the side of the head. During parallel imaging applications a significant improvement can be still observed in presence of the high-permittivity helmet, but some SNR reduction is observed in the head when high acceleration factors are performed.| File | Dimensione | Formato | |
