Multi-physics modeling of organs in motion (imaging and therapy)

Résumé

A dynamic research activity has been developed for 15 years around organ motion modeling, gathering 2 laboratories of the LabEx PRIMES (LIRIS and IP2I Lyon). This activity was supported by LabEx PRIMES which allowed us to build an original unified patient-specific approach, based on tetrahedral elements, allowing simultaneous movement quantification of the respiratory system, 4D dose distribution (on-line) and tomographic reconstruction for PET imaging (off-line). In our approach, all the physical quantities: deformation of the organs, their densities, deposited dose and nuclear activities for PET imaging, are assigned to the vertices of the tetrahedrons. We believe that our approach can potentially open interesting perspectives for other imaging techniques.
