BACKGROUND: Oral and maxillofacial surgery currently relies on virtual surgery planning based on image data (CT, MRI). Three-dimensional (3D) visualizations are typically used to plan and predict the outcome of complex surgical procedures. To translate the virtual surgical plan to the operating room, it is either converted into physical 3D-printed guides or directly translated using real-time navigation systems. PURPOSE: This study aims to improve the translation of the virtual surgery plan to a surgical procedure, such as oncologic or trauma surgery, in terms of accuracy and speed. Here we report an augmented reality visualization technique for image-guided surgery. It describes how surgeons can visualize and interact with the virtual surgery plan and navigation data while in the operating room. The user friendliness and usability is objectified by a formal user study that compared our augmented reality assisted technique to the gold standard setup of a perioperative navigation system (Brainlab). Moreover, accuracy of typical navigation tasks as reaching landmarks and following trajectories is compared. RESULTS: Overall completion time of navigation tasks was 1.71 times faster using augmented reality (P = .034). Accuracy improved significantly using augmented reality (P < .001), for reaching physical landmarks a less strong correlation was found (P = .087). Although the participants were relatively unfamiliar with VR/AR (rated 2.25/5) and gesture-based interaction (rated 2/5), they reported that navigation tasks become easier to perform using augmented reality (difficulty Brainlab rated 3.25/5, HoloLens 2.4/5). CONCLUSION: The proposed workflow can be used in a wide range of image-guided surgery procedures as an addition to existing verified image guidance systems. Results of this user study imply that our technique enables typical navigation tasks to be performed faster and more accurately compared to the current gold standard. In addition, qualitative feedback on our augmented reality assisted technique was more positive compared to the standard setup.?>.
背景：口腔颌面外科目前依赖于基于图像数据（CT、MRI）的虚拟手术规划。三维（3D）可视化通常用于规划和预测复杂手术的结果。为了将虚拟手术计划转换到手术室，它要么转换为物理 3D 打印的导板，要么直接使用实时导航系统进行转换。
目的：本研究旨在提高虚拟手术计划向手术过程（如肿瘤学或创伤手术）的翻译准确性和速度。这里我们报告了一种用于图像引导手术的增强现实可视化技术。它描述了外科医生如何在手术室中可视化和交互虚拟手术计划和导航数据。通过将我们的增强现实辅助技术与围手术期导航系统（Brainlab）的黄金标准设置进行正式的用户研究，来客观地评估用户友好性和可用性。此外，还比较了典型导航任务的准确性，例如到达地标和跟踪轨迹。
结果：使用增强现实技术，导航任务的总完成时间快了 1.71 倍（P=0.034）。使用增强现实技术，准确性显著提高（P<0.001），而对于到达物理地标，相关性较弱（P=0.087）。尽管参与者对 VR/AR（评分为 2.25/5）和基于手势的交互（评分为 2/5）相对不熟悉，但他们报告说，使用增强现实技术，导航任务变得更容易执行（使用 Brainlab 评定为 3.25/5，HoloLens 2.4/5）。
结论：所提出的工作流程可用于广泛的图像引导手术程序，作为现有验证的图像引导系统的补充。这项用户研究的结果表明，与当前的黄金标准相比，我们的技术可以使典型的导航任务更快、更准确地执行。此外，与标准设置相比，对我们的增强现实辅助技术的定性反馈更为积极。
