Lattice Boltzmann method for modelling of biological phenomena.

This paper suggests a new methodology based on the Lattice Boltzmann Method for the modelling of complex biomechanical systems. The LBM can be applied for different operations due to the matching of the pixels of medical images with the nodes of the lattice used by the Lattice Boltzmann method. This allows the optimisation and reduction of the computation time when solving multiphysics complex phenomena. To demonstrate the efficiency of the chosen approach, the modelling of the thrombosis phenomenon within the cavity of a giant cerebral aneurysm has been implemented. The underlying strategy is to implement the Lattice Boltzmann Method for different operations such as extracting the geometry of a considered aneurysm associated to its parent vessel, solving fluid dynamics governing the blood How and modelling the thrombus growth.
