新冠疫情下医学影像设备的虚拟仿真实验项目建设

Construction of Virtual Simulation Experiment Project of Medical Imaging Equipment under the Novel Coronavirus Pneumonia Epidemic

目的针对医学影像设备特点建设虚拟仿真实验项目,以适应新冠疫情下的实验教学。方法根据医学影像设备的成像原理,完全用数学公式来阐述各种图像信号的产生过程、数据采集过程以及图像重建过程,再将各种实验项目和规律现象,系统集成并运行在网络上。结果开发出和CT设备相关的6个虚拟仿真实验项目,基本包含了CT设备相关的实验内容,满足了网上教学和学生自主学习的需要。结论新冠疫情下,针对医学影像设备的虚拟仿真实验项目建设,能很好地适应线上线下教学的需要。

Objective According to the characteristics of medical imaging equipment,a virtual simulation experiment project was built to adapt to the experimental teaching under the coronavirus pneumonia epidemic situation.Methods According to the imaging principle of medical imaging equipment,the generation process,data acquisition process and image reconstruction process of various image signals were described completely by mathematical formula.Then,various experimental items and regular phenomena were integrated and operated on the network.Results Six virtual simulation experiment projects related to CT equipment were developed,which basically included the experiment contents related to CT equipment,and met the needs of online teaching and autonomous learning.Conclusion Under the coronavirus pneumonia epidemic situation,the construction of virtual simulation experiment project for medical imaging equipment can meet the needs of online and offline teaching.
