The importance of modern imaging techniques for capturing detailed structural information of a biological system cannot be understated. Unfortunately images do not reveal the “full functional story” and a spatially realistic computer model is often necessary for a comprehensive understanding of the complicated structural and physiological properties of the biological system’s entities under investigation. Deeper insights into structure-to-function relationships of different entities is achieved via finite element simulations of the modeled biomedical process. A 3D (three dimensional) finite element meshed computer model of the biological system is therefore a first step to perform such simulations. Toward that goal, we here at the CVC, have developed a unified modeling paradigm that starts with an imaging data and builds a geometric model of the biological entity under investigation for this to be used in further analysis and simulation.
