Development Of CT Clinical And Applied Teaching System Based On Virtual Simulation

With the increasing 3D processing power of computers and the emergence of inexpensive sensing and display components,virtual simulation technology is widely used in a wide range of applications,and the beautiful blueprint presented to everyone.In virtual simulation,model creation and 3D scene creation are the premise and guarantee,and the top priority for the application of virtual simulation technology.The purpose of this paper is to study the virtual simulation technology,taking CT clinical and applied teaching platform based on virtual simulation technology as an example,to set up 3d model in virtual reality and structure improvement、CT and clinical application of virtual animation、looking for model makes the balance between design and animation and 3d models in the virtual simulation environment condition and several key technical problems such as trigger statement for the answers.In this paper,with the help of Autodesk 3ds MAX,Photoscan and MakeHuman and other tools,through cross-platform cooperation and transplantation,a set of thinking framework for 3d reconstruction of characters and application models in virtual simulation scene is set up.This paper proposes solutions to the problems in the design and programming of virtual characters and model animation,and provides strong technical support for the construction of characters and models between platforms and the man-machine interaction between operators in the virtual simulation environment.Moreover,after in-depth exploration of the Unity3 D virtual engine and its script development framework in the early stage,we formed the development idea of the clinical and applied teaching platform based on the virtual simulation CT.First,according to the operator group and the teaching content,the demand and the analysis results are realized.The virtual simulation teaching platform mainly simulates CT clinical application,imaging principle,image reconstruction(reverse projection method),and CT development history.It focuses on human-computer interaction.With the combination of training and inspection,training can be conducted in a controlled and repeatable way anytime and anywhere to deepen CT clinical and application knowledge.At the same time,the training samples are configured,the training teaching resources are improved,and the medical teaching ideas and contents are pushed to the new.Secondly,according to the results of demand analysis,the function of the teaching platform is distinguished,so as to obtain four functional modules of interface management,model management,task management and data management.For the four functional modules to carry out the detailed design of the entire platform,so as to achieve the six tasks of the system.Finally,Unity3 D virtual engine and Visual Studio2017 are used to script the platform to achieve the functional requirements of the entire teaching platformThe establishment and realization of CT clinical and applied teaching platform with the help of virtual simulation technology provide a different teaching method for medical image practice teaching.The establishment and realization of CT clinical and applied teaching platform with the help of virtual simulation technology provide a different teaching method for medical image practice teaching.
