Pelvic organ modeling is a main goal towards a better pathophysiological understanding, and further it could help for the preoperative planning. However, the organ modeling faces the problem of determining the soft tissue biomechanical parameters. In the context of pelvic floor diseases, a patient-specific modeling of the pelvic organ dynamics has been performed. The model achieved mainly reproduces the pelvic organ behavior during a strain. In order to correct the organ models used, we propose a methodology to quantitatively assess the accuracy of the simulation. The approach relies on the comparison of the simulated organ behaviors to the corresponding organ behaviors observed on a dynamic MRI sequence obtained from the same patient. For this purpose, complementary criteria are presented, they summarize the movements and deformations undergone by the pelvic organs during a strain.
