....of surgical instruments can be visualized. 1 Introduction The idea of estimating soft tissue deformation due to bone realignment was formulated by Vannier in 1983 [26] In 1992 further approaches to surgery simulation were introduced by Kikinis [16, 1] followed by Delingette in 1994 [8, 9, 7], Bohner in 1996 [3] Koch in 1996 [17] and Bro Nielsen in 1998 [4] These approaches use deformable volumes, mass spring models, or finite elements to predict soft tissue changes. In this paper, a method for direct computation of soft tissue deformation based on a mass spring model is ....

....ffl 3) passive aided surgery: it is passive in the sense that the computer aids the surgeon by displaying useful information but does not intervene in the diagnosis or surgery process itself. If atlas visualization and registration are added to a surgery simulation program (craniofacial surgery [DSCP94] or stereotactic surgery [Har94] the user can manipulate more easily the patient data thanks to automatic labeling and to contrast the patient data with the normalized atlas. A medical doctor can then plan surgical procedures. Moreover, if the registration algorithm can work in real time (at ....

He derived the two stioeness parameters of biphasic springs from stress strain curves described in a biomechanical study [KGEB75] Similarly, Delingette et al. [DSCP94] represented fat tissue elasticity as a network of springs on a 3 simplex mesh. Keeve et al.

....During the operation an electromagnetic tracking system with 6 DOF determines the 3D position of the patient. 2. PURPOSE In the past, several basic approaches have been investigated for a 3D segmentation to cut skull fragments in volume data using VR techniques. For example, Delingette et al. [2] used the virtual hand user interface, by which the cutting tool follows the motion of the user s hand, which is tracked by an electromagnetic sensor. However, most of these approaches lack force and haptic feedback to enhance the realism of their simulations. As the technology improves and the ....

....In a long term period, such statistics could be sent to a diagnosis module that could detect some pathologies. For now, we plan to integrate the 3D visualization of the crest lines of the skull and the atlas in the craniofacial surgery simulation testbed developed in the Epidaure project [DSCJ94] in order to help the physician to plan operations. 3 The atlas structure 3.1 The features Raw medical images are stored in a discrete 3D matrix I = f(x; y; z) By thresholding I , isosurfaces of organs are computed (for instance, the surface of the skull for CT Scan, of the brain or the ....
