Fig. 5From: A review of 3D first-pass, whole-heart, myocardial perfusion cardiovascular magnetic resonanceThe UNFOLD filter. Example frequency distribution of a more dynamic (a) and less dynamic (b) region of a cardiac dataset. In the cases of undersampling, resulting in aliasing, the small dynamic region and low undersampling factor allows the unwanted aliasing-induced sidelobes to be removed via a simple filter (c).
