Simulating Mechanism of Brain Injury During Closed Head Impactad, which consists of three layers: the rigid skull, the cerebrospinal fluid and the solid brain. The fluid behavior is governed by the Navier-Stokes equations, and the fluid and solid interact together according to the laws of mechanics. Numerical simulations are then performed on this model to sim

Segmentation and 3D Reconstruction Approaches for the Design of Laparoscopic Augmented Reality Envirre proposed to be employed for extracting useful information to help surgeons performing the operating techniques. This work introduces an illumination model into the design of automatic segmentation algorithms and 3D reconstruction methods. Results obtained from the implementation of our methods to

Deforming a High-Resolution Mesh in Real-Time by Mapping onto a Low-Resolution Physical Model well below the desired mesh density for visual realism. Previous work avoids this problem by using a high-resolution visual mesh mapped onto a low-resolution physical model. We apply the same approach and present an computationally cheap implementation of a known algorithm to avoid texture artefact

Versatile Design of Changing Mesh Topologies for Surgery Simulational-time constraints implemented in the SOFA [4] platform. The proposed design is based on a simulation tree gathering software components acting on a mesh. The mesh topology is described by a topological component which also provides algorithms for performing topological changes (cutting, refinement

Contact Model for Haptic Medical Simulations deformations on soft tissues, they modify the boundary conditions of the models and will mainly modify their behavior. Yet, most recent work has focused on the more precise modeling of soft tissues while improving efficiency; but this effort is ruined if boundary conditions are ill-defined. In this

Estimation of the Fracture Toughness of Soft Tissue from Needle Insertionue. The model captures a mechanical process where the sharp needle produces a crack that is opened to accommodate the shaft of the needle. This process involves the interchange of energy between four distinct phenomena: the work done by the needle, the irreversible work of fracture, the work of fric

Towards a Framework for Assessing Deformable Models in Medical Simulations. Thus, the number of complex models describing the mechanical behavior of medical environments have increased these last years. While the development of advanced computational tools has led to interesting modeling algorithms, the relevances of these models are often criticized due to incomplete mo

Land-Ocean Systems in the Siberian Arctic particular, parametric studies were carried out in order to quantify the influence of constitutive model parameters of muscles. The model described in this paper might be used for simulation of plastic and reconstructive surgery and for investigation of the physiology and pathology of face deformation.

Physical and Chemical Principles,ion. Then, we present our original method to compute a deformation field that considers the abdominal and thoracic breathing influence. Finally, we show on two human data that our simulation model can predict several organs position at 50 Hz with accuracy within 2-3 mm.
