To compare the volumetric GRAPPA algorithms in the presence of
physiological artifacts, five different algorithms were used, i.e.,
2D-GRAPPA-OP, 3D-GRAPPA, EX-3D-GRAPPA and SK-3D-GRAPPA. The performance of
algorithms were compared using the root mean squared error (RMSE) of the image reconstructed
from fully acquired 3D in-vivo k-space data and the image reconstructed using
different reconstruction algorithms from undersampled dataset.
