Develop the first systematic approaches to quantifying uncertainty due to the geometry of the organ in biomechanics simulations. Discretise the body using NURBS and use the control points and their weights as geometrical descriptors of the shape of the organ. This will allow us to quantify the uncertainties due to the lack of knowledge of the geometry of the organ. Collaboration with ESR08 (membrane cutting) and ESR12 (bulk cutting simulations based on NURBS approximations). The work will address the automated creation of simulation models for biomechanics, at the geometrical level, by empowering the definition of patient-specific geometrical descriptions of organs for biomedical simulations.).
A toolbox to quantify uncertainties in biomechanics simulations.
