Improved peripheral SNR achievable with the 32-channel sleeve antenna receiver array compared to a 32-channel loop receiver array of similar dimensions at 10.5 tesla.

Fig. 4. Intrinsic SNR (iSNR) maps of the 32-channel loop array (a) and 32-channel sleeve antenna (b) arrays with phantom in the axial, coronal, and sagittal plane. Ratio maps (c) between (b) and (a) and profiles (d) along the indicated lines.
