The use of surgical simulator systems for education and preoperative planning is likely to increase in the future. A natural course of development of these systems is to incorporate patient specific anatomical models. This step requires some kind of segmentation process in which the different anatomical parts are extracted. Anatomical datasets are, however, usually very large and manual process...

We present our methodology for the three-dimensional anatomical and geometrical description of soft tissues, relevant for orthopaedic surgical applications and musculoskeletal biomechanics. The technique involves the segmentation and geometrical description of muscles and neurovascular structures from high-resolution computer tomography scanning for the reconstruction of generic anatomical mode...

Visible Productions, Ltd., of Fort Collins, CO, and other companies produce polygon-based, 3-D models of organic structures in humans and animals. There is already a large database of excellent 3-D anatomical models existing that was created at high expense. Figure 1 shows several of the many polygon-based models created by Visible Productions. These models are used primarily for educational us...

In this article, we are interested in the modelling of the lower limb anatomical structures such as bones, muscles and tendons. The proposed method starts with an MRI acquisition during which the lower limb of a subject is scanned. 3D models are generated after a manual segmentation of the anatomical structures. However, the surface of the generated models appears not to be smooth. Furthermore,...

The main purpose of this work is to investigate a simple way of making polydimensiloxane (PDMS) anatomically artery models such as a carotid arteries with and without aneurysm. By using a human carotid computerized tomography (TC) it was possible to develop 3D anatomical models through the application of a rapid prototyping (RP) technique, known as tridimensional printing (TDP). By combining th...

We present a method based on graphical models for the localization of corresponding anatomical landmarks in CT images of multiple patients for which only limited labeled training data is available. Our method mobilizes anatomical spatial relationships learnt from labeled training images in order to improve dense matching using weak landmark appearance descriptors. In this study, we report resul...

In this paper we describe the latest developments of the hepatic surgery simulator prototype developed at INRIA The goal of this simulator is to provide a real istic training testbed for performing laparoscopic pro cedures Therefore its main functionality is to allow to cut and deform tridimensional anatomical models with the help of two virtual laparoscopic surgical in struments Thoughout this...
