Context<\/h4>\n

Radiotherapy<\/b> and Hadrontherapy<\/b> are techniques which are efficient to cure local cancerous tumours. They consist in delivering a lethal dose of ionising beam to the cancerous volume, while reducing impact on surrounding healthy tissues. Such treatments need accurate targeting necessitating a precise knowledge of the shape and position of tumours.<\/p>\n

Collaborations<\/h4>\n

This work is part of the ETOILE project<\/a> a consortium team aiming to build a Hadrontherapy Centre in France.<\/p>\n

Results<\/h4>\n

Lung model is customized to patient with 3D CT-Scan data and elasticity measurement<\/b> [1, <\/a> 2]<\/a>. Breathing was simulated with continuous mechanics laws and solved with finite element method<\/b>. The mesh was adapted to the context preserving the CT-scan voxel and presenting smooth edges for external geometry [3]<\/a>. Boundary conditions were defined by anatomists and medical experts to actually reproduce lung behaviour during the respiration process [4, <\/a> 5]<\/a>.
\nFinally, the model produces better results with regards to other 3D Bio-CAD models published in the literature [6]<\/a>. Elsewhere, a tool has been developed to convert the predicted geometrical states into 4D CT-scan<\/b> which is crucial information to plan the treatment sessions [7, <\/a> 8]<\/a>.<\/p>\n
