VivoForce instrument for retinal microsurgery

Simon Nessim Henein, Charles Baur, Marine Chantal Elisabeth Geneviève Clogenson, Sebastian Krzysztof Fifanski, José Luis Rivera Gutiérrez

2017

Needle for invasive medical use and needle assembly

Simon Nessim Henein, Charles Baur

A needle for invasive medical use includes a long extended cylindrical needle shaft having an axis and an outer surface area, with a short shaft end at a first end of the shaft with a beveled tip with a pointed end, and a needle hub attached to a second en ...

A statistical shape model of the human second cervical vertebra

Simon Nessim Henein, Charles Baur, Reto Meuli, Marine Chantal Elisabeth Geneviève Clogenson

Statistical shape and appearance models play an important role in reducing the segmentation processing time of a vertebra and in improving results for 3D model development. Here, we describe the different steps in generating a statistical shape model (SSM) ...

Real-Time Update of 3D Deformable Models for Computer Aided Liver Surgery

Charles Baur, Benoît Dagon

Providing accurate image-guidance for soft-tissue interventions remains a complex task. Most of the time, preoperative models and planning data are no more valid during the surgical process due to motions and deformations of the organ of interest. In this ...

Identifying physical properties of deformable objects by using particle filters

Charles Baur, Oussama Khatib

This paper presents a new approach for estimating physical properties of deformable models from experimental measurements. In contrast to most previous work, we introduce a new method based on particle filters which identifies the different stiffness prope ...

A Framework for Intraoperative Update of 3D Deformable Models in Liver Surgery

Charles Baur, Benoît Dagon

Efficient computer assisted surgery dealing with soft tissues remains a complex task. In most cases, the preoperative information such as 3D organ reconstructions and the planning built upon are no longer valid during the surgical process itself due to the ...

Fast Wavelet based Ultrasound Image Segmentation for Liver Vessels Extraction

Charles Baur, Benoît Dagon

A method for extracting in real-time the position and size of liver vessels from 2D ultrasound images is described. It proceeds in two steps. Starting with a rough localization of the vessels using the scale-space theory, seed points are defined. Then, ves ...

Endoscopic navigation for minimally invasive suturing

Charles Baur, Gábor Székely

Manipulating small objects such as needles, screws or plates inside the human body during minimally invasive surgery can be very difficult for less experienced surgeons due to the loss of 3D depth perception. Classical navigation techniques are often incap ...

Robust Method for Real-time, Continuous, 3D Detection of Obstructed Faces in Indoors Environments

Sébastien Grange, Charles Baur

We address the need for robust detection of obstructed human features in complex environments, with a focus on intelligent surgical UIs. In our setup, real-time detection is used to find features without the help of local (spatial or temporal) information. ...
