Purpose: To improve the quality control skills of radiotherapy staff and medical students and to reduce the radiation risk of training, this study developed a remote training system for quality control of medical electronic linear accelerators based on virtual reality (VR) and augmented reality (AR) technology.
Methods: This training system built a training system for radiotherapy techniques and the five major quality control contents of medical electronic linear accelerators, and created virtual reality interactive software using Unity 3D. It developed a multi-terminal platform for AR glasses and PC, and built a remote control module. A multi-perspective evaluation system was adopted and a questionnaire was designed to analyse the application value of the system.
Results: This training system built a multi-terminal virtual simulation training system with radiotherapy technology as well as quality control knowledge system, which could be used to learn through AR glasses, PC virtual simulation and VR virtual simulation, and could realize 5G remote control of medical electronic linear accelerator for off-site quality control demonstration and guidance. As of 01/03/2022, the system had accumulated 133 training sessions and 66 valid questionnaires on the application of the system were returned, of which 90.91% (60/66) of the respondents trusted the experimental results shown by the system and 87.88% (58/66) of the respondents considered the training system necessary.
Conclusion: The training system in this study was based on the needs of talent training and responds to the development of new information technology. Combined with advanced research and development means, it restored the live environment and physical objects of the medical electronic linear accelerator treatment room in high definition rigorously and scientifically. It realized virtual-real interactive radiotherapy quality control training, reduces the training radiation hazard and promoted the reform and progress of the training model fundamentally.
