We reconstructed the breathing NCAT phantom images from 9.25 times undersampled k-space data using 12 lines in polar trajectories. The figure shows reconstructed images of the 10th frames by local TV Fig.(a), nonlocal 2D Fig.(b), nonlocal 3D Fig.(c). Comparing with the original image Fig.(d), the nonlocal algorithms preserve more details while standard TV introduces patchy artifacts.
