2D-SENSE-GRAPPA is presented as a method to reconstruct
in-plane accelerated simultaneous multislice data in a
single step rather than sequentially unaliasing each
dimension. Following a recent adaptation of Sice-GRAPPA
by Setsompop et al, the method uses different kernels
for the odd and even lines of k-space to ensure
robustness against EPI N/2 ghosting. Reconstruction
quality is very similar to Sice-GRAPPA but owing to its
one-step approach, 2D-SENSE-GRAPPA has the potential to
reduce calculation times which are becoming a problem in
fMRI and DTI.
