In this work, wave-CAIPI sampling is incorporated in a 3D variable flip angle turbo spin echo (TSE) sequence optimized for ultra high field applications. The acquired wave-CAIPI data are reconstructed with a GRAPPA-based wave-CAIPI reconstruction algorithm using multiple reconstruction kernels. Highly accelerated wave-CAIPI TSE images with 1 mm3 resolution and whole brain coverage are acquired at a 7 Tesla scanner. A clear SNR improvement compared to Cartesian CAIPIRINHA is shown.
