Abstract
The Temporal Bone Dissection Simulator is an ongoing project funded by a grant from The National Institute on Deafness and other Communication Disorders (NIDCD) to construct a dissection simulator of the regional anatomy of the temporal bone. The goal of this project is to create a virtual performance environment for dissection of temporal bone with a focus on preoperative assessment and surgical planning. The simulator will be used in efficacy studies through integration with an otolaryngology curriculum, with eventual extension to simulation of surgical procedures. Through the use of leading edge visualization technology and by incorporating aspects of an intelligent tutor, the simulation system provides a means for learning temporal bone anatomy and surgical procedures while maintaining a surgical context. This document presents a summary of the current state of the project. The temporal bone is identified, and motivation for a virtual dissection simulation provided. Parallel research is described, and the approach of this project presented. Three techniques that address specific problems encountered in the development of the dissection simulator are introduced. The first technique provides a method for rendering a five channel segmented volume while interactively modifying the visibility of each segment. This technique is necessary for aspects of the incorporated intelligent tutor. The second technique provides a means for improving volume rendering from rates during local modification. This technique solves the problem of maintaining sufficient interactivity while a virtual dissection is in progress. The third technique supplies an extra modality to volume interaction by providing simple haptic (force) feedback of volumetric data. This technique is required in order to increase realism and provide an appropriate tactile response to the user. The current status of the project is presented, along with preliminary user feedback and future goals.
