In this study, the effects of the aspect ratio of ACS lines with respect to the phase-encoding and partition-encoding steps are investigated for 3D GRAPPA reconstruction algorithms such as EX-3D-GRAPPA and SK-3D-GRAPPA. When the ACS lines are acquired by carefully considering the dimensions of the image matrices, the quality of the reconstructed images can be improved.
