Inverse problems in 1D hemodynamics on systemic networks: a sequential approach

Damiano Lombardi

Abstract

In this work a sequential approach based on the Unscented Kalman Filter is applied to solve inverse problems in 1D hemodynamics, on a systemic network. For instance, the arterial stiffness is estimated by exploiting cross sectional area and mean speed observations in several locations of the arteries. The results are compared to those ones obtained by estimating the Pulse Wave Velocity and the Moens-Korteweg formula. In the last section, a perspective concerning the identification of the terminal models parameters and peripheral circulation (modeled by a Windkessel circuit) is presented.
Une approche sequentielle basée sur le filtrage de Kalman Unscented est appliquée à la résolution des problèmes inverse en hémodynamique des réseaux artériels. Les propriétés mécaniques des artères sont estimées à partir des mesures d'écoulement. Les résultats sont comparés à ceux que l'on obtient en mesurant la Pulse Wave Velocity. Une perspective concernant l'estimation des modèles de circulation périphérique est proposée dans la dernière partie.
