Reconstructed axial images of patient 4: Column (a) was reconstructed without motion compensation, and columns (b)–(d) were obtained after the 1, 3, and 9 ME-MCR iterations, respectively. Two fast motion phases 25% and 35% R-R and three reference phases 5%, 40%, and 75% R-R are shown. The insets are the zoom-in of the box (right coronary region).
