Using Salomé to reproduce the structure and to observe the diffusion of water molecules in biological tissue

Abstract

Diffusion magnetic resonance imaging (DMRI) can give useful information on cellular structure and its structural changes. Salomé is used to reproduce some complicated shapes in d-dimensions (d=2,3) that are used to represent the natural structures of various biological tissue. The meshes representing these shapes are used as inputs to a finite element code that we built upon FENICS C++. Results were obtained for a model of globlastoma (cerebral tumor) as a Voronoi diagram which was used to observe the convergence of the apparent diffusion tensor in long-time limit to the effective diffusion tensor computed by homogenization theory.
