Fig. 2: The modelling process and results.

a Vascular skeleton line. b Endpoints and intersections on the skeleton line. c Vascular boundary. d The model highlights a part. e Model protruding silhouette. f After adjusting the highlighted outline. g Pressure distribution just after blood flow into blood vessels. h Pressure distribution where most of the blood flow has entered the blood vessel. i Vascular pressure distribution at the end of blood flow. j Too many contours on the skeleton line cause crossover. k Sample optic disc area vascular model.
