Endovascular Guidewire Flexibility Simulation
Endovascular clinicians use guidewires to navigate within vessels during angiography or angioplasty. In mastering this core skill, an alternative to the traditional apprenticeship in patients is provided by vi...

A Virtual Environment for Core Skills Training in Vascular Interventional Radiology
We present a prototype for a new virtual environment aiming at training interventional radiologists in the core skills involved in using catheters or guidewires. The instrument is modelled as a hybrid mass-spr...

A Finite Element Study of the Influence of the Osteotomy Surface on the Backward Displacement during Exophthalmia Reduction
Exophthalmia is characterized by a protrusion of the eyeball. The most frequent surgery consists in an osteotomy of the orbit walls to increase the orbital volume and to retrieve a normal eye position. Only a ...

Indentation for Estimating the Human Tongue Soft Tissues Constitutive Law: Application to a 3D Biomechanical Model
A 3D biomechanical model of the tongue is presented here. Its goal is to evaluate the speech control model. This model was designed considering three constraints: speech movement speed, tongue movements and to...

Evaluation of the exophthalmia reduction with a finite element model
The exophthalmia is a pathology defined by an excessive forward protrusion of the ocular globe [1]. For disthyroidy exophthalmia, a surgery is usually needed, once the endocrinal situation has been stabilized. A ...

Simulation of the Exophthalmia Reduction Using a Finite Element Model of the Orbital Soft Tissues
This paper proposes a computer-assisted system for the surgical treatment of exophthalmia. This treatment is classically characterized by a decompression of the orbit, by the mean of an orbital walls osteotomy...
