“…We activate the pointshells that are colliding the jawbone and we compute their contribution to the drilling. The local erosion follows an analytical model that is close 6 to the one proposed by [11]. After the integration of the erosion analytical model, we store a new density for each concerned voxel (in evaluateDensity(P) function in figure 2).…”

Abstract. Training systems for dental implantology that are based on virtual reality need a precise haptic feedback with six Degrees of Freedom (6DoF) This is particularly challenging when using real patient data for the jawbone and during the interactive simulation of drilling. In this paper, we present our simulator and two complementary contributions: The first one is a method for 6DoF haptic rendering of contacts between the drilling tool and the jawbone model issued from a CT-scan. The second one is a fast simulation of the jawbone erosion during drilling which is relevant for 6DoF haptic rendering.

Abstract. We describe a framework for training-oriented simulation of temporal bone surgery. Bone dissection is simulated visually and haptically, using a hybrid data representation that allows smooth surfaces to be maintained for graphic rendering while volumetric data is used for haptic feedback. Novel sources of feedback are incorporated into the simulation platform, including synthetic drill sounds based on experimental data and simulated monitoring of virtual nerve bundles. Realistic behavior is modeled for a variety of surgical drill burrs, rendering the environment suitable for training low-level drilling skills. The system allows two users to independently observe and manipulate a common model, and allows one user to experience the forces generated by the other's contact with the bone surface. This permits an instructor to remotely observe a trainee and provide real-time feedback and demonstration.

“…Our surgical simulation framework and scripting language have been applied to the development of a mastoidectomy training system, similar to [13]. A mastoidectomy is a procedure performed in which a portion of the temporal bone is drilled away in order to provide access to inner regions of the ear.…”

Abstract. Existing surgical simulators provide a physical simulation that can help a trainee develop the hand-eye coordination and motor skills necessary for specific tasks, such as cutting or suturing. However, it is equally important for a surgeon to gain experience in the cognitive processes involved in performing an entire procedure. The surgeon must be able to perform the correct tasks in the correct sequence, and must be able to quickly and appropriately respond to any unexpected events or mistakes. It would be beneficial for a surgical procedure simulation to expose the training surgeon to difficult situations only rarely encountered in actual patients. We present here a framework for a fullprocedure surgical simulator that incorporates an ability to detect discrete events, and that uses these events to track the logical flow of the procedure as performed by the trainee. In addition, we are developing a scripting language that allows an experienced surgeon to precisely specify the logical flow of a procedure without the need for programming. The utility of the framework is illustrated through its application to a mastoidectomy.
