Medical Image Analysis, 11/09/09
Ahn B et al. – Measurements were carried out with a three–dimensional optical system and a force transducer. Using the surface deformation and force response results, authors estimated the maximum radius of influence, which can be utilized to determine the minimal required soft tissue model size for the FEM simulation. Considering the influence of the boundary conditions, the model was designed and integrated into an inverse FEM optimization algorithm to estimate the model parameters. The mechanical behavior of large deformations was characterized with FE modeling via hyperelastic and linear viscoelastic models.
