Based on registered and segmented medical image data, methods for modelling anatomical structures (blood vessels, tissue, skin, …) are investigated. In addition to the 3-dimensional structures in the form of surface and volume meshes, relevant model parameters such as elasticity values are included in the modelling.
On the basis of these models, methods for characterizing the anatomical structure depicted in the model are developed. The methods used for this purpose range from geometric methods (e.g. distances between elements, diameters, etc.) to real-time non-linear numerical simulation (flow behaviour, elastic deformation, etc.).
These models are used, for example, in simulators for the education and training of physicians. For this purpose the models are made comprehensible with virtual and hybrid interaction possibilities and visualized accordingly. For example, the neurosurgical clipping operation is simulated here.
