A 2D representation of the in-house vessel generation algorithm developed. A A single root segment is created. B The closest point (red cross) from the cloud of terminal random points is selected to be added to the existing tree. C After the tree is updated, the next closest point to the existing tree is selected. D, E The vascular tree is grown by connecting a new pipe to the existing tree and updating all hemodynamics and geometrical parameters. F The final tree is constructed, and the algorithm stops when there are no more terminal points to connect to the tree
