Rat mesentery, based on a montage of micrographs. This is “Network A,” with 913 segments and 652 nodes, as described in: Pries, A.R., Secomb, T.W., Gaehtgens, P. and Gross, J.F. Blood flow in microvascular networks – Experiments and simulation. Circulation Research 67: 826-834 (1990).

Format of data file: Segment Node Node diam. length No. name from to 1 * 999 1 35 348.9
Segments and nodes (end points of segments) are numbered. Each row in the network data file refers to one segment. Segment diameter and length are given in microns. In this network each segment terminates in bifurcations at both ends, or is a feeding/draining vessel. Segments are generally not straight. The spatial coordinates of the nodes were not measured in this network. and no graphical representation is available. The following image is derived from a photomontage of a similar network in the rat mesentery.
