Research On Behavior Simulation In Virtual Training System For Medical Treatment Process

Virtual training system of medical treatment process is one application of the virtual reality in medical field. The main objective is to use the computer technology to simulate the behaviors during the medical treatment process , so as to construct a visualized environment for learning.Meanwhile, the system can meet the needs of experimental training of the medical education.The real medical process contains numerous movements of organs, the reactions of patients, treating behavior of doctors and their interactive behaviors, etc. In order to enhance the virtual training system highly immersive sense, it is necessary to conduct more simulated.This dissertation based on the delivery process as an example, analysis and studies some key technologies of the medical virtual training system and the implementation methods of virtual medical training process system. We focus to find a new methed for the virtual behavior modeling of the medical process and movement planning. A prototype system was achived based on these methods. The main contribution is showed below:(1) We analyze the design objectives of the medical virtual training system, describe the modules' function of the system, study the technology programs and the development platform of the system.(2) We studies several key technologies issues of the medical virtual training system about the geometric modeling, physical modeling, behavioral modeling the entire process, including construction of the medical virtual environment, Skeleton system of the human motion simulation, key frame control based on the cubic spline interpolation, soft object simulation, and make decisions related to those technologies.(3) We study the design concept and implementation methods of the medical process planning and simulation. Firstly, based on the matrix transform principle of the medical operation space, we combined the key frame technology of cubic spline interpolation with the dynamic-model loading techniques. Then, we accomplished the medical behavior modeling and motion process planning and medical research simulation.Finally, based on the platform of VC++6.0, Eon Studio 5.0, JavaScrpit and Windows XP, the prototype of visualized and interactive training in the virtual environment system was accomplished. This system can be used for medical treatment process simulation, medical treatment planning, virtual training in the medical treatment process in experimental training.
