| Objective To solve the difficult problem of experimental teaching of MRI equipment by independently designing a virtual simulation teaching system for performance testing of medical magnetic resonance imaging (MRI) equipment. Methods A total of 202 students of Batch 2016 majoring in 4-year medical imaging technology and 5-year medical imaging of Binzhou Medical University. According to the teaching requirements of MRI equipment in Medical Imaging Equipment Science, a 3D experimental simulation model and experimental scenes were established based on Unity3D engine by using Unity3D, 3D Studio Max, Maya and Visual Studio technology to design experimental learning content and assessment content, develop the teaching system software and perform Web-based online learning. Then, the satisfaction survey on experimental learning was conducted, the statistics of the experimental results of the teaching system on the national virtual simulation experiment teaching platform was collected and the learning effects were evaluated in multiple dimensions. Results The virtual simulation teaching system was a comprehensive experiment with 12 knowledge points, 12 experimental items and a total of 81 interactive contents and steps. The overall satisfaction rate of 202 students in our school was 96.82%(2 347/2 424). Among the 499 subjects who participated in the learning of the teaching system on the national virtual simulation experiment teaching platform and submitted the experimental report, the average score of the experiment was 78.07 points (the full score of online learning assessment was 90 points), and the overall passing rate was 96.79%(483/499). The average learning time of the 18 students who got 90 points was 54 min. Conclusion This virtual simulation teaching system possesses comprehensive experimental contents with high fidelity of experimental scenes and strong interactivity of experimental operation, prospecting great learning effects and promotion value. |
