Virtuella vävnadsobjekt för medicinska träningsapplikationer
This Master thesis discusses the development of a virtual human soft tissue object for use in exercise applications of various medical procedures.The soft tissue object to be developed shall look like, feel like and behave as living human tissue. It shall give the user a realistic feeling of weight, softness and roughness, and shall behave in a correct way for exercise purposes. The soft tissue model is to be used in a three dimensional stereo graphic environment with haptic feedback. A prototype for practicing the procedure of inserting a catheter is built. The prototype is used to evaluate the potential of the virtual environment for medical exercise applications, and to assess the realism and usability of the soft tissue object. This prototype is also used to specify requirements of a future software application for practicing a multitude of medical procedures in the medical education program of the Swedish defense.The parameterized and general tissue object developed in this masters work is also successfully assessed by, amongst others, surgeons from Huddinge University Hospital as a model for the internal organs for a laparoscopic cholesystectomy operation.
