Abstract:Objective To improve the operation skills of radiotherapy staff and students of related majors, and further promote
the development of precision radiotherapy, a virtual simulation teaching and training system for image guided radiotherapy error
analysis was designed and implemented. Methods Based on unity 3D to build VR model, using C# language and vs2017 compiler
programming to research and develop the process of image acquisition and matching of stereotactic radiotherapy. VR scene
construction, learning tips, test answer, virtual software page and action trigger design were focused on, which were divided into
teaching mode and assessment mode. The online scoring system was used to record the usage and upload it to “Experimental Space”
for test feedback, and the questionnaire was designed to analyze the application value of the system. Results The development
of the system has been completed. From November 2019 to July 2020, the number of experimental visitors was 14985, and the
number of experimental tests was 489, with a passing rate of 86.7%. A total of 84 valid questionnaires of experimental application
value survey were collected, 90.47% of them thought that it was necessary to develop virtual simulation teaching platform of image
guided radiotherapy, and 90.48% thought that they could master knowledge points. Conclusion The application of virtual simulation
technology to the experimental course of image guided error analysis of radiotherapy technology is feasible and worth popularizing.
