Abstract


A framework for virtual reality based training of puncture interventions is presented. The system uses a haptic device with six degrees of freedom (6DOF) to enable realistic force sensations during needle insertions into virtual patients. A manifold of different visualization techniques gives new insights into the anatomy of the punctured region. The 3D effect is enhanced by stereoscopic visualization. An evaluation component rates the quality of virtual punctures to give the user feedback and improvement suggestions. Currently the system supports the training of three different puncture tasks. Two of them have been evaluated in a pilot user study with 55 participants. The questionnaire based study indicates a high user acceptance.
