Mechanical role of pleura on lung motion during breathing
Résumé
Organs motions, in particular due to patient's breathing are crucial for the accuracy of radiotherapy and hadrontherapy treatments. We developped a pulmonary motion simulation (Villard et al.2006) based on continuous mechanical framework. A key point of our model is the inclusion of the pleura action, letting the lungs slide agains the chest wall during the simulation of the respiration toquantify the actual role of the pleura on the lung motion. We compared the imulation of the lung displacements obtaines by allowing or blocking these slidings.
