Abstract

Starting from non invasive experimental measurements by Doppler echotracking, the human arterial tree of a given patient is numerically reconstructed.The chosen approach consists in building a simplified fluid/structure interaction model for each artery and to find the parameters of the network by solving an inverse problem. The first reconstruction results of the lower arterial tree of a healthy patient are given and show a very good agreement with the echotracking measurements. Such numerical reconstruction, that includes in particular the estimation of the stiffness of each artery, will help for an early diagnosis of cardiovascular diseases.
