dc.description.abstract-translatedVisualization and interaction with 3D bone models reconstructed from medical images are fundamental for biomedical applications. They are useful for surgeons in order to diagnose and plan surgical operations. Although traditional reconstruction techniques based on isosurfacing are mainly used for visualization, it is desirable to obtain labelled models without outliers in order to improve the interaction. This paper presents the integration of digital image processing and computer graphics techniques to enable not only the reconstruction of simplified 3D bone models, but also the interaction with them. To that end, the segmentation of CT images is performed in order to obtain different bone regions and to label them. This approach is divided into three main parts: segmentation, reconstruction and interaction. The goal of the segmentation is to extract closed contours and to generate labelled regions which represent the bone structures to be reconstructed. Then, 3D bone models are obtained from these regions by isosurfacing. Finally, a detailed collision detection can be calculated between the 3Dmodels in the scene in order to provide visual aid when the user is interacting with them. This interaction includes the calculation of distances, nearest points and overlapping triangles. Moreover, an immersive experience is provided by integrating the Leonar3Do stereo system.en
