Rendering of the full dataset Kidney 1 (a), the foreground segmentation of the arterial vessel tree created using a hierarchical variant of the random walker method [18] down to a vessel radius of roughly \(10\,\upmu \hbox {m}\) (b) and the symbolic rendering of the vessel network topology extracted with the proposed method (c). Vessel segments connecting two branching points (blue) or end points (orange) are rendered using cylinders whose color encodes the mean average radius
