摘要：

随着教育数字化的加快推进，数字化资源及其应用平台搭建日益受到重视。针对磁共振教学培训中存在的难题，基于数字孪生五维模型概念，构建磁共振成像设备数字孪生五维模型框架。提出一种基于机理模型的建模仿真方法。使用物理实体获取多维物理数据完成数字人建模，提出虚拟采集和图像重建方法生成图像，并利用融合数据进行迭代优化，实现了检查前准备、线圈选择、体位摆位、参数设置、图像处理等全流程三维可视化操作。基于自旋回波、梯度回波和平面回波成像序列开展了应用验证，在实时数据驱动下，仿真结果与实体设备运行结果相一致，满足了教学培训和辅助设计需求，为规模化教学的个性化学习和智能自适应学习提供了资源保障。

Abstract:

With the accelerating digitalization in education, the construction of digital resources and application platforms has caught increasing attention. The framework of MRI equipment digital twin five-dimensional model is constructed to solve the problems in teaching and training for magnetic resonance imaging (MRI). A modeling and simulation method based on the mechanism model is proposed. The multi-dimensional physical data are obtained to perform digital human modeling, and the virtual acquisition and image reconstruction method is proposed to generate images. The digital twin data are adopted for iterative optimization to implement the whole process of the three-dimensional visual operation including preparation before inspection, coil selection, patient positioning, parameter setting, and image processing.Application verification is carried out based on the imaging sequences of spin echo, gradient echo, and echo planar. Driven by real-time data, the simulation results are consistent with the operation data of the physical equipment. This meets the needs of teaching training and auxiliary design and guarantees personalized and intelligent adaptive learning under massive teaching arrangements.

Key words: digital twin, magnetic resonance imaging, sequence, mechanism modeling
