Fast 3D Model Update for the Compensation of Soft Tissue Deformation in Image Guided Liver Surgery

Benoît Dagon

Today, the use of computer assistance to guide surgeon's gestures becomes increasingly common for interventions on rigid organs such as the hips and vertebrae. Guidance information is provided through the representation of the position of surgical instrume ...

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 ...

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 ...

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 In most cases, the preoperative information such as 3D organ reconstructions and the planning built upon are no longer valid during the surgical process itself due to the ...
