摘要： 目的 探讨裸眼3D增强现实(augmented reality,AR)教学辅助系统在临床医学专业本科生医学影像学课程教学中的应用效果。方法 2023至2024年,采用试验对照方法,在空军军医大学2018级和2019级八年制临床医学专业四年级学员中开展医学影像学教学研究。将2019级52名学员设为试验组,利用基于裸眼3D技术的AR教学辅助系统开展教学;将2018级50名学员设为对照组,采用传统教学方式。采用课程考核和问卷调查方法评价两组学员的医学影像学教学效果。采用t检验和Mann-Whitney U检验分析数据。结果 试验组学员的医学影像学理论考核成绩、实践阅片成绩和总成绩均高于对照组学员[(62.1±3.1)分比(59.8±3.4)分,(22.9±2.4)分比(21.1±2.6)分,(85.0±4.6)分比(80.9±6.0)分],其差异均具有统计学意义(均P＜0.05)。试验组学员对课堂趣味性、满意度、参与度、学习效果和易于理解的评分均高于对照组学员[5.0(1.0)分比4.0(2.0)分,5.0(1.0)分比4.0(2.0)分,5.0(1.0)分比3.5(1.0)分,5.0(1.0)分比4.0(2.0)分,5.0(1.0)分比4.0(1.0)分],其差异均具有统计学意义(均P＜0.05);试验组学员对基于裸眼3D技术的AR教学辅助系统的便利度和继续使用意愿评分均较高[均为5.0(1.0)分]。结论 基于裸眼3D技术的AR教学辅助系统用于临床医学专业本科生医学影像学课程教学是一种全新、高效的教学方式,有助于提高教学效果,激发学员学习兴趣,提高学员学习效率,具有良好的应用前景。

Abstract: Objective To explore the application of naked eye 3D Augmented Reality (AR) teaching assistant system in medical imaging for undergraduates. Methods From 2023 to 2024, medical imaging teaching research were carried out among the fourth-year students of the eight-year clinical medicine major of 2018 and 2019 grades in Air Force Medical University through experimental control methods. Fifty-two students from the 2019 grade were assigned to the study group, and the AR teaching auxiliary system based on naked-eye 3D technology were used for teaching, while 50 students from the 2018 grade were assigned to the control group and taught through traditional teaching methods. Course assessment and questionnaire survey were used to evaluate the teaching effect of medical imaging among the two groups of students. T-test and Mann-Whitney U test were used to analyze the data. Results The knowledge examination, practical skills testing and total scores of the experimental group were higher than those of the control group [(62.1±3.1) vs. (59.8±3.4), (22.9±2.4) vs. (21.1±2.6), (85.0±4.6) vs. (80.9±6.0), all P<0.05]. The Likert scores in interest, satisfaction, participation, learning effect and ease of understanding of students in the naked eye 3D AR assisted teaching group were all higher than those in the control group [5.0 (1.0) vs 4.0 (2.0), 5.0 (1.0) vs 4.0 (2.0), 5.0 (1.0) vs 3.5 (1.0), 5.0 (1.0) vs 4.0 (2.0), 5.0 (1.0) vs 4.0 (1.0), all P<0.05], and scores of the convenience of using the naked eye 3D AR medical imaging teaching assistance system APP and willingness to continue to use the software were high in the experimental group [both were 5.0 (1.0)]. Conclusions AR teaching assistance system based on naked eye 3D technology is a new and efficient teaching model for medical imaging for undergraduates. Compared with traditional teaching methods, it helps to improve students' learning interest, increase teaching interaction, improve teaching effect, and has a good application prospect.
