在过去的几十年里，手术导航系统经历了巨大的发展，以最大限度地降低风险并提高手术的精度。如今，基于增强现实（AR）的手术导航是一种很有前景的临床应用技术。在 AR 系统中，虚拟现实和现实现实混合在一起，为用户提供各种信息的实时、高质量可视化（Moussa 等，2012）[1]。例如，软组织、血管和神经等虚拟解剖结构可以与现实世界场景实时集成。在这项研究中，使用光学透视HMD（头戴式显示器）开发了基于AR的手术导航系统（AR-SNS），旨在提高手术的安全性和可靠性。通过使用该系统，包括仪器的校准、配准和头显的校准，头戴式显示器中的3D虚拟关键解剖结构在术中运动跟踪过程中与现实场景中患者的实际结构对齐。精度验证实验表明，平均距离和角度误差分别为0.809±0.05mm和1.038°±0.05°，足以满足临床要求。 (C) 2015 Elsevier Inc. 保留所有权利。
The surgical navigation system has experienced tremendous development over the past decades for minimizing the risks and improving the precision of the surgery. Nowadays, Augmented Reality (AR)-based surgical navigation is a promising technology for clinical applications. In the AR system, virtual and actual reality are mixed, offering real-time, high-quality visualization of an extensive variety of information to the users (Moussa et al., 2012) [1]. For example, virtual anatomical structures such as soft tissues, blood vessels and nerves can be integrated with the real-world scenario in real time. In this study, an AR-based surgical navigation system (AR-SNS) is developed using an optical see-through HMD (head-mounted display), aiming at improving the safety and reliability of the surgery. With the use of this system, including the calibration of instruments, registration, and the calibration of HMD, the 3D virtual critical anatomical structures in the head-mounted display are aligned with the actual structures of patient in real-world scenario during the intra-operative motion tracking process. The accuracy verification experiment demonstrated that the mean distance and angular errors were respectively 0.809 +/- 0.05 mm and 1.038 degrees +/- 0.05 degrees, which was sufficient to meet the clinical requirements.
