A Preliminary Study For A Biomechanical Model Of The Respiratory System

Engineering and Computational Sciences for Medical Imaging in Oncology - ECSMIO is the special session 1 of International Conference on Computer Vision Theory and Applications - VISAPP 2010International audienceTumour motion is an essential source of error for treatment planning in radiation therapy. This motion is mostly due to patient respiration. To account for tumour motion, we propose a solution that is based on the biomechanical modelling of the respiratory system. To compute deformations and displacements, we use continuous mechanics laws solved with the finite element method. In this paper, we propose a preliminary study of a complete model of the respiratory system including lungs, chest wall and a simple model of the diaphragm. This feasibility study is achieved by using the data of a "virtual patient". Results are in accordance with the anatomic reality, showing the feasibility of a complete model of the respiratory system
