Patient-Specific Modeling of Pelvic System from MRI for Numerical Simulation: Validation Using a Physical Model

Numerical simulation is useful to help understand the behavior of pelvic system, and eventually to assist the diagnostic and surgery. Patient-specific simulation is expected to optimize the treatment of patients. Despite the requirement of mechanical properties and loading, patient-specific simulation requires first 3D geometry adapted to patient. Manual 3D reconstruction of the patient-specific anatomy is time-consuming and introduces uncertainties. In this paper, we propose an efficient computer-assisted approach to modeling 3D geometries well suited to MRI data. A well-controlled physical model is also proposed, and manufactured, to estimate uncertainties of the presented method.
