虚拟现实技术在放疗技术教学中的应用

目的 基于现有的放疗技术课程教学模式理论与实践的矛盾,探讨虚拟现实(VR)技术在放疗技术创新课程中应用的必要性和可行性。方法 在深入分析现有学科教学模式的特点下,引入VR技术,基于VR设计软件、眼镜、操作手柄等搭建专用的可交互平台,可通过手机端增强现实(AR)、头盔端AR、触摸屏、PC虚拟仿真以及VR虚拟仿真等多种形式的课程学习,并进行放疗六大流程的实训测试,分析该技术在放疗技术人才培养中的可行性。结果 经过软硬件的设计及测试结果分析,线上教学可应用编写交互程序,搭建虚拟体验场景,制作课程资源库,构建实训类课程和教学体系等实现;线下实践测试可应用在反馈整个流程的模拟学习,具有可行性及开发价值,可应用于放疗技术的理论和实践教学中,使教学更加简便、生动直观。结论 VR技术与放疗技术的人才培养相结合,可通过平面及虚拟仿真技术进行线上及线下课程的理论和实践教学,具有方便快捷,效率高的优点,值得大力推广。

Application of virtual reality technology in teaching course of radiotherapy technology

Objective To discuss the necessity and feasibility of application of virtual reality (VR) technology in the teaching course of radiotherapy technology based on the contradictions between the theory and practice of current teaching mode. Methods After in-depth analysis of the characteristics of the existing disciplinary teaching mode,VR technology was introduced to design software,glasses,operating handles and establish a special interactive platform. The teaching courses could be delivered via mobile phone side AR,helmet and AR,touch screen and PC virtual simulation with VR virtual simulation,etc. Six processes of radiotherapy were tested through online courses and offline groups to analyze the feasibility of this technology applied in the training of radiotherapy professionals. Results After the design of software and hardware and the analysis of test results,the online teaching could be utilized to write interactive programs,build virtual experience scenes,create course resource database and construct practical training courses and teaching system. The offline practice test could be applied to the simulation learning of feedback of the whole process,which possessed feasibility and development value. It could be applied to the theory and practice teaching of radiation therapy technology,making the teaching more convenient,vivid and intuitive. Conclusions VR technique combined with radiotherapy technology training can be delivered through online and offline teaching courses of theory and practice by using the plane and virtual simulation technology,which is convenient,quick and highly efficient and deserves widespread application.
