摘要
目的研发一种用于医用电子直线加速器质量保证(QA)的多终端虚拟仿真远程培训系统,以提高放疗工作人员及医学生的QA操作技能,并降低培训辐射危险。方法运用Unity 3D扩展现实(XR)技术制作虚拟现实交互软件,基于放疗技术以及医用电子直线加速器质量控制内容搭建培训系统,开发多终端使用平台,并搭建远程控制模块。采用多角度评价体系,并设计调查问卷,分析该系统的应用价值。结果本系统还原医用电子直线加速器治疗室现场环境和实物,可实现对加速器5G远程控制,进行非现场的QA演示与指导。截至2022年3月1日,系统累计培训133人次,收回系统应用有效问卷76份,其中90.79%(69/76)的调查对象对系统显示的实验结果表示信任,并有88.16%(67/76)的调查对象认为该培训系统是必要的。结论本培训系统培训效果反映良好,从根本上降低了培训辐射危险,可为加速器QA培训模式的改革和进步提供参考。
Objective To improve the quality assurance(QA)skills of radiotherapy personnel and medical students and reduce the radiation risk of training by developing a remote training system for QA of medical electronic linear accelerators.Methods This training system was built based on radiotherapy technology and quality control contents of medical electronic linear accelerators,and a virtual reality interactive software was developed using extended reality(XR)technology Unity 3D.A remote control module of multi-terminal platform was also developed.A multi-perspective evaluation system was adopted and a questionnaire was designed to analyze the application value of this system.Results The training system reproduced the live environment and physical objects of medical electronic linear accelerator treatment room.It built a multi-terminal virtual simulation training system with radiotherapy technology as well as QA knowledge system.This system could provide 5G remote control of medical electronic linear accelerator for off-site quality control demonstration and guidance.By March 1,2022,a total number of 133 people had been trained using this system,76 valid questionnaires had been taken,of which 90.79%(69/76)of the respondents trusted the experimental results shown by the system and 88.16%(67/76)of the respondents considered the training system necessary.Conclusions The training effect of this system is widely recognized.It fundamentally reduces the training radiation hazard and provides reference for the reform and progress of QA training mode of medical electronic linear accelerators.
