The First Computational Anatomy Seminar



Session 1 "Simulators for Surgical and Dental Training"

  • Invited Speaker : Dr. Andreas Pommert
    (Head, VOXEL-MAN group, University Medical Center Hamburg-Eppendorf, GERMANY)
    • Abstract
      • Would you like to fly with a pilot who has never done any flight simulator training? While simulators were introduced to the airline industry already decades ago, virtual reality simulators for training and rehearsal of difficult or dangerous surgical interventions are relatively new. In this presentation, methods for drilling and milling of hard tissues such as bone, cartilage and teeth at a computer screen are reviewed. This involves the segmentation, modeling and visualization of the human body, its modification with simulated medical instruments, and the control of these instruments with a force feedback device, which is also used to provide a realistic haptic feel. Benefits of this approach are illustrated with the examples of VOXEL-MAN TempoSurg?, a simulator for surgical access to the middle ear, which is already being used in places as diverse as China, Germany, India, Japan, Saudi Arabia and the United Kingdom, and a simulator for caries removal, which is currently being developed. It is shown how these simulators will improve the quality of training, while also reducing the costs of education.

Session 2. "Application of anatomical models to diagnosis and prediction"

  • Invited Speaker : Dr. Rainer Schubert
    (Professor, University for Health Informatics and Technology Tyrolin Innsbruck, AUSTRIA)
    • Abstract
      • Applications of biomedical image processing and analysis to clinical tasks in diagnosis and therapy planning are frequently restricted by the problem of inter-individual differences in terms of variation in structure, topology and shape. At several stages in typical pipelines this restriction occurs, beginning with segmentation of the individual anatomical structure or organ followed by the problem of distinguishing "normal" from pathological variations of the structure and typically ending in the problem of deriving valid diagnostic and prognostic information. The talk will start with a rehearsal of the ideas and methods underlying the VOXEL-MAN anatomy atlases and will discuss it's limitations for being applied to clinical tasks in diagnosis. Based on this summary the main part of the talk will focus on our approaches and results to model shape and micro-structure variation of patient populations and the application for segmentation, classification, diagnosis and prediction. This part will be concluded by a current example in model based diagnosis of osteoporosis and predicting fracture risk and implant anchorage. The presentation will be finished by an outlook on preliminary ideas on combining shape models with symbolic mereo-topological models as a step towards a complete operational description of the macroscopic phenotype variation.
