Study on Realization of Simulative Operation System Based on 3D Alternation Technology

With the advancement of means of medicine, surgical is developing to micro trauma (to patients) and few contacts (to doctors). Without a great lot of training, doctors are difficult to adapt to this new mode. The systemic research into simulative operation applies itself to resolve these matters. The emphasis on research of the article is pivotal technique of simulation surgery. The main research contents in this thesis include medicine-image preprocessing, surface reconstruction from medical images, 3D alternation technic in simulation surgery. The emphasis of this thesis is 3D alternation technic realized with software, the transformation formulation of world coordination system and screen coordination system is listed. It´s the foundation of 3D interaction and actualization of 3D measurement results. A 3D alternation frame based on 3D Widgets is advanced, controlling the mouse´s freedom and picking method based on parallel perspective are used to realize the special characteristic points picking. A 3D interaction system in VC++ is developed, and the test and application result shows that it reaches predictive effects.
