摘要
目的:探讨增强现实技术在口腔颌面颈部解剖识别中的应用效果.方法:以北京大学2020级口腔医学专业本科生为实验对象,选择口腔颌面颈部解剖相关知识为实验内容.根据实验内容选择影像数据,通过数字化软件对影像数据中上下颌骨、颈部动静脉等重要血管和骨组织结构进行三维重建,生成解剖实验模型,将重建模型加密后储存于云端.通过联网移动设备扫描实验模型对应的二维码,获取增强现实图像,辅助实验人员讲解和实验对象学习.分别在理论讲解和实践操作中应用增强现实技术,以课后问卷调查的形式收集实验对象对于增强现实技术的应用反馈,评价该技术辅助口腔颌面颈部解剖识别中的应用效果.结果:实验共纳入83名本科生,所有实验对象均能顺利使用增强现实技术识别口腔颌面颈部解剖结构.实验参与人员均可通过联网的移动设备扫描二维码,从云端获取三维解剖实验模型,并在移动端对模型进行放大、缩小、旋转等操作.增强现实技术能够以不同的解剖部位内容为基础,制定个性化的内容呈递方式,通过更为真实的三维立体图像帮助实验对象分辨解剖结构,获取解剖知识.课后问卷调查结果显示,学生对于增强现实技术辅助口腔颌面颈部解剖结构识别的接受程度较高(9.19分),增强现实技术在培养学生三维空间理解能力(9.01分)、提升课程趣味和激发学习热情方面(8.55分)获得了较高评分.结论:增强现实技术能够实现解剖模型的三维可视化,激发学生学习热情,辅助学生更好建立三维空间理解能力,在帮助学生进行口腔颌面颈部解剖结构识别过程中取得了良好的应用效果.
Abstract
Objective:To evaluate the outcome of Augmented reality technology in the recognizing of oral and maxillofacial anatomy.Methods:This study was conducted on the undergraduate students in Peking University School of Stomatology who were learning oral and maxillofacial anatomy.The image da-ta were selected according to the experiment content,and the important blood vessels and bone tissue structures,such as upper and lower jaws,neck arteries and veins were reconstructed in 3D(3-dimension-al)by digital software to generate experiment models,and the reconstructed models were encrypted and stored in the cloud.The QR(quick response)code corresponding to the 3D model was scanned by a net-worked mobile device to obtain augmented reality images to assist experimenters in teaching and subjects in recognizing.Augmented reality technology was applied in both the theoretical explanation and cadaveric dissection respectively.Subjects'feedback was collected in the form of a post-class question-naire to evaluate the effectiveness of augmented reality technology-assisted recognizing.Results:In the study,83 undergraduate students were included as subjects in this study.Augmented reality technology could be successfully applied in the recognizing of oral and maxillofacial anatomy.All the subjects could scan the QR code through a connected mobile device to get the 3D anatomy model from the cloud,and zoom in/out/rotate the model on the mobile.Augmented reality technology could provide personalized 3D model,based on learners'needs and abilities.The results of likert scale showed that augmented reality technology was highly recognized by the students(9.19 points),and got high scores in terms of forming a three-dimensional sense and stimulating the enthusiasm for learning(9.01 and 8.85 points respective-ly).Conclusion:Augmented reality technology can realize the three-dimensional visualization of impor-tant structures of oral and maxillofacial anatomy and stimulate students'enthusiasm for learning.Be-sides,it can assist students in building three-dimensional space imagination of the anatomy of oral and maxillofacial area.The application of augmented reality technology achieves favorable effect in the recog-nizing of oral and maxillofacial anatomy.
