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
