Improved modelling of blood flow in the brain

By combining the skills of mathematicians, physicists and computer specialists, scientists1Laboratoire de Mathématiques de Reims (Université Reims Champagne-Ardenne/CNRS), Institut de Recherche Mathématique Avancée (CNRS/Université de Strasbourg), Laboratoire Jean Kuntzmann (CNRS/Grenoble INP/Inria/Université Grenoble Alpes), Kitware SAS developed a system that can reconstruct in virtual images the human cerebral blood flow. Starting from the MRI of volunteers, researchers first established a three-dimensional map of the cerebral blood network. Algorithms designed to model the structure of the arteries and veins then allowed the blood flow to be visualized in a fashion that was both realistic and simplified. This virtualization of blood flow opens many perspectives in the medical sector. It could in particular help evaluate the potential effects of a surgical operation in patients suffering from a vascular condition.
