Pre-operative pulmonary LPM generation. A resistance Ri is computed for each ith outlet of the 3D model (a) by means of steady simulations (velocity-colored pathlines are displayed); Ri is first converted in a morphometric-based sub-tree (b), then in the corresponding Womersely-based impedance RCRi (c). PSA = single atrium pressure; Rp = proximal resistance; Rd = distal resistance; C = compliance.
