解剖学教育是形成未来医学专业人员的一个具有挑战性但至关重要的因素。在这项工作中，开发了一个个性化和交互式增强现实系统，以促进教育。该系统表现为魔镜，其允许用户身体上的解剖结构的个性化原位可视化。CT数据集的实时体积可视化创建了用户可以查看其身体内部的错觉。该系统包括RGB-D传感器作为实时跟踪设备，以检测在显示器前面移动的用户。此外，魔镜系统还显示了用户可以与之交互的文本信息、医学图像和器官的3D模型。通过7名临床医生和72名学生的参与，设计了两个用户研究，分别评估魔镜系统的教育精度和可接受性。第一项研究的结果表明，增强现实覆盖在用户身体上的平均精度为0.96厘米，而第二项研究的结果表明，86.1%的人认可魔镜的教育价值，91.7%的人认可三维显示器官的增强现实能力。这种独特类型的个性化增强现实技术的实用性已在本文中得到证明。临床解剖学29：446-453，2016年。(c)2015 Wiley Periodicals，Inc.
Anatomy education is a challenging but vital element in forming future medical professionals. In this work, a personalized and interactive augmented reality system is developed to facilitate education. This system behaves as a magic mirror which allows personalized in-situ visualization of anatomy on the user's body. Real-time volume visualization of a CT dataset creates the illusion that the user can look inside their body. The system comprises a RGB-D sensor as a real-time tracking device to detect the user moving in front of a display. In addition, the magic mirror system shows text information, medical images, and 3D models of organs that the user can interact with. Through the participation of 7 clinicians and 72 students, two user studies were designed to respectively assess the precision and acceptability of the magic mirror system for education. The results of the first study demonstrated that the average precision of the augmented reality overlay on the user body was 0.96 cm, while the results of the second study indicate 86.1% approval for the educational value of the magic mirror, and 91.7% approval for the augmented reality capability of displaying organs in three dimensions. The usefulness of this unique type of personalized augmented reality technology has been demonstrated in this paper. Clin. Anat. 29:446-453, 2016. (c) 2015 Wiley Periodicals, Inc.
