Purpose. We created a virtual assistant chatbot that will serve as a tool for radiation safety training for clinical staff, including radiation oncologist, radiotherapist and medical physicist, in cancer treatment. The Bot can also be used to test their knowledge on radiation safety. Methods. The Bot was constructed using IBM’s Watson Assistant functionalities on the IBM cloud. A layered structure approach was used in the workflow of the Bot to interact with the user. Through answering various questions concerning radiation safety in radiotherapy, the users can learn the essential information to gain knowledge, when working in a cancer centre/hospital. Results. The user interface of the Bot was a front-end window operating on Internet, which could easily be accessed by any Internet-of-things such as smartphone, tablet or laptop. The Bot could communicate with the user for radiation safety Q&A. If the Bot could not identify what the user needed, the Bot would provide a list of options as a guidance. Using the natural language processing in communication, knowledge transfer from the Bot to user could be carried out. Conclusion. It is concluded that the radiation safety chatbot worked as intended, utilizing all the tools provided by the IBM Watson Assistant. The Bot could provide radiation safety information to the radiation staff effectively, and be used in staff training in radiotherapy.

目的。我们创建了一个虚拟助理聊天机器人，它将作为一种工具，为临床工作人员（包括放射肿瘤学家、放射治疗师和医学物理学家）提供癌症治疗方面的放射安全培训。Bot 还可用于测试他们对辐射安全的了解。方法。Bot 是使用 IBM 云上的 IBM Watson Assistant 功能构建的。在 Bot 的工作流程中使用分层结构方法与用户进行交互。通过回答有关放射治疗中辐射安全的各种问题，用户可以在癌症中心/医院工作时了解基本信息以获得知识。结果. Bot 的用户界面是一个在互联网上运行的前端窗口，可以被任何物联网，如智能手机、平板电脑或笔记本电脑轻松访问。机器人可以与用户沟通进行辐射安全问答。如果 Bot 无法识别用户需要什么，则 Bot 将提供选项列表作为指导。在通信中使用自然语言处理，可以进行从机器人到用户的知识转移。结论。得出的结论是，辐射安全聊天机器人利用 IBM Watson Assistant 提供的所有工具按预期工作。该机器人可以有效地向放射人员提供放射安全信息，并用于放射治疗人员的培训。
