From: Distortion correction using topup algorithm by single k-space (TASK) for echo planar imaging
Comparison between before and after the distortion correction. The comparison was conducted for both (a) 3D 1sh-CenEPI in Subject #2 and (b) 2D 1sh-Cen EPI with matrix size of 96 × 96. (c) Magnified images of 2D 1sh-Cen EPI images are shown with the ground truth brain boundary from GRE images (orange line).
