Realistic surgical simulation requires both visual and biomechanical fidelity. In this paper, a technique is described where patient specific deformation can be incorporated into finite element modelling. Time dependant tissue deformation is captured in vivo via video bronchoscopy and estimated using image feature tracking. This motion is factored into rigid and non-rigid components via 2D/3D registration based on bronchoscope video and 3D tomographic reconstruction of the same patient. Non-rigid deformation is decomposed into a linear combination of localised deformations due to regional forces. Through optimisation, the forces are scaled over time to derive a physically plausible deformation without having to invert the finite element equations or minimising a system with a large degree of freedom. Error analysis demonstrates the viability of the method to reproduce deformations similar to that observed in bronchoscope video. Detailed analysis is provided for assessing the robustness of the method in the presence of outliers and missing landmarks.
