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.
