Abstract [en]

Intra-operative experiments are performed for mechanical characterization of human organs using the so called "aspiration test". Mechanical parameters are determined from the experimental data that are useful for medical simulation as well as for diagnostic purposes. The inverse problem is solved in order to determine the parameter of constitutive equations that account for viscoelastic or viscoplastic tissue response at large deformations. The results of clinical studies with measurements of the mechanical response of human liver and uterine cervix are summarized.
