High-Permittivity materials have been recently used to shape the B1 field distribution to enhance SNR and transmit efficiency. So far, these materials have been mainly applied to increase SNR in the head. In this work, through numerical simulations, we explore the possibility to use high-permittivity pads to improve the signal in the chest. The pads are positioned between the model of the coils (8 TEM transmit coils and 24 receive loops) and of the human body. Our simulations show that some improvement can be obtained by adding the pads to the coils.
