Figure 2.

Results of the anti-aliasing algorithm on aliased image slices of the aorta and main pulmonary artery (MPA) demonstrating the first, second, third, and fifth iterations of the algorithm on a heavily aliased velocity image. Initially aliased areas are circled in black. No further aliasing is identified by the algorithm beyond the fifth iteration (panel D) and the code terminates, leaving panel D as the final corrected image.
