摘　　要：作为元宇宙的重要底层技术之一,数字孪生与各种实验教学的结合正在加快落地。CT检查技术是医学影像技术专业的一个重要课程模块,但在实验教学中存在过度依赖医院实体设备、实验机时十分有限、检查过程环节多、规范多、缺乏交互性等现实难题。该文构建了一种基于机理建模和数字人体模型相结合的数字孪生CT检查技术虚拟仿真平台,展示了平台框架结构和模型基础,介绍了部分仿真案例和功能模块,并分析了使用该平台的教学效果。该平台不仅打破了学习时空的限制,还提供了沉浸式、多角度的CT检查技术实验环境,有助于开展相关专业的实验教学,赋能教育新形态,改善实践新体验。As one of the important underlying technologies of the metaverse,Digital Twin technology is accelerating the integration with various experimental teaching methods.CT examination technology is an important course module in the field of medical imaging technology.However,there are practical difficulties in its experimental teaching,such as excessive reliance on hospital real physical equipment,limited experimental machine time,multiple standardized imaging and examination processes,and lack of interactivity.This article constructs a Digital Twin based CT examination technology virtual simulation platform that combines mechanism modeling and digital human body modeling.The platform framework structure and model foundation are presented,some simulation cases and functional modules are introduced,and the teaching effect of the platform is analyzed.This platform not only expands the limitations of learning time and space,but also provides an immersive and multi-angle CT examination technology experimental environment,which helps to carry out experimental teaching in related majors,empowers new forms of education,and enhances new practical experiences.
