The main challenges of UHF imaging are RF absorption and B1+ inhomogeneity, and increased patient coil interactions. These issues can impact the feasibility as we as the quality of power hungry T2 weighted sequences. In addition, the limitation of 8KW RF power amplifiers on most UHF human MRI scanner presents serious challenges for achieving high quality T2 weighted imaging. Here we present a non-patient specific multi-slab imaging approach optimized for SAR as well as input power that achieves homogenous whole head 7T TSE and FLAIR
