Fill-time image $t_d(x,y)$ corresponding to Fig. 9(a). The components indicated are identifiable by understanding Fig. 2 and knowing: (1) the FV has the earliest fill, so it is the darkest vessel in the lesion and (2) the CN, DVs, and NCDVs are progressively downstream and have progressively later fills, so they become progressively brighter.
