Abstract

Using the method of constrained constructive optimization, we have generated a series of anatomically similar, realistically branching arterial vessel trees which feed the same per fusion area but differ in the number of arterial segments. In order to consistently parameterize vessels of different size, the elastic properties for the individual segments were derived from a simple model depending solely on vessel radii. Simulations of the hemodynamics of these trees were performed by means of an equivalent electric network model, in which each vessel segment was either regarded as a microcompartment and replaced by a single electric circuit; alternative
