基于Unity3D的CT虚拟仿真实验系统

CT Virtual Simulation Experiment System Based on Unity3D

为克服CT(电子计算机断层扫描)实验教学受设备、场地的限制,促进学生理解CT的实验原理与操作步骤,本文采用Unity3D软件与交互式技术,开发适用于多平台的CT虚拟仿真实验系统。其具有以下突出特点:一是交互性好;二是可以立体、动态地呈现实验过程;三是可以记录操作过程与参数设置,并自动生成实验过程记录。实践表明,在本系统中,实验者仅需要通过鼠标、键盘即可完成实验,然后由实验过程记录反馈实验成绩。这有利于学生实践能力的提高,便于学生自查,便于教师分析教学情况,最终可提高实验教学质量。

In order to overcome the limitations of equipment and site for CT(electronic computer tomography)experi⁃mental teaching,and to promote students'understanding of the experimental principles and operating procedures of CT,this paper used Unity3D software and interactive technology to develop a CT virtual simulation experimental sys⁃tem suitable for multiple platforms.It has the following outstanding features:one is good interactivity;the other is that the experiment process can be presented in a three-dimensional and dynamic manner;the third is that it can record the operation process and parameter settings,and automatically generate a record of the experiment process.Practice shows that in this system,the experimenter only needs to use the mouse and keyboard to complete the experiment,and then the experimental results are recorded and fed back by the experiment process.This is conducive to the im⁃provement of students'practical ability,facilitates students'self-examination,facilitates teachers to analyze teaching conditions,and ultimately improves the quality of experimental teaching.
