Abstract:

 

Recent results from projects in tele-immersion and in augmented visualization for breast biopsies have inspired a new project with far more ambitious goals: improving advanced surgical training by immersive tele-presence within pre-recorded trauma cases.In this collaboration between UNC, Brown University, University of Pennsylvania, and the Pittsburgh Supercomputing Center, we are building a system for recording the events in a surgical theater with 50-100 video cameras. After the recordings, an instructor should be able to edit and enhance the immersive 3D recordings with hypermedia aids for later class demonstrations and independent immersive student study.We are developing new techniques for continuously recording the activities in the surgical theater, for saving indicated periods of interest, for reconstructing3D time sequences (with some regions in great detail), for rendering these detailed reconstructionsin real-time, and for presenting the stereo images using head-mounted displays and projectors.Although portions of these capabilities have already been demonstrated by our group and others, performing all the steps simultaneously (from acquisition to presentation to interaction) poses unprecedented technical challenges. If successful, however, such tele-immersive systems should enable a wide variety of training, consultation and collaboration activities, including a particular interest of ours, real-time surgical consultation over long distances.
