目的：创建一个增强现实(AR)应用程序，帮助介入放射学(IR)的医务人员学习如何正确使用天花板悬挂的辐射屏蔽屏，并从学习者动机的角度测试其实用性。方法：使用AR应用程序在三种设置下可视化血管造影室内的散射辐射分布：不使用天花板悬挂式辐射屏蔽屏(错误)；屏蔽屏底部边缘与患者躯干之间存在间隙(错误)；屏蔽屏底部边缘与患者躯干之间没有间隙(正确)。33名医务人员使用了这一AR应用程序，之后进行了基于John Keller的ARCS(注意力、相关性、信心和满意度的四种类别)动机模型的教学材料动机调查(IMMS)，该模型由36个项目组成，反应在5分(1-5)Likert量表上。结果：总体得分为4.67+/-0.30(平均+/-标准差)。医生在注意力、相关性和满意度方面的得分往往低于其他医务人员(无统计学意义)。结论：从学习者动机的角度来看，AR应用程序学习如何正确使用天花板悬挂的辐射屏蔽屏得到了很高的评价。
Purpose: An augmented reality (AR) application to help medical staff involved in interventional radiology (IR) learn how to properly use ceiling-suspended radiation shielding screens was created, and its utility was tested from the perspective of learner motivation. Method: The distribution of scattered radiation in an angiography room was visualized with an AR application in three settings: when a ceiling-suspended radiation shielding screen is not used (incorrect); when there is a gap between the bottom edge of the shielding screen and the patient's torso (incorrect); and when there is no gap between the bottom edge of the shielding screen and the patient's torso (correct). This AR application was used by 33 medical staff, after which an Instructional Materials Motivation Survey (IMMS) based on the John Keller's ARCS (four categories of Attention, Relevance, Confidence, and Satisfaction) Motivation Model, consisting of 36items with responses on a 5-point (1-5) Likert scale, was conducted. Results: The overall score was a high 4.67 +/- 0.30 (mean +/- standard deviation). Physician's scores tended to be lower than those of other medical staff in the categories of Attention, Relevance, and Satisfaction (not statistically significant). Conclusions: The AR application to learn how to properly use ceiling-suspended radiation shielding screens was highly rated from the perspective of learner motivation.
