Several correction methods (e.g. direct combination,
PEN) have been proposed to reduce slab boundary
artifacts in 3D multi-slab diffusion imaging. However,
these methods are only capable of removing aliasing
artifacts and require long scan time. In this work, a
method compatible with optimal TRs is proposed to reduce
slab boundary artifacts by jointly estimating slab
profile and image. Initial results show the superior
performance of our proposed method over the other two
methods.
