Several visualization methods for intraoperative navigation systems were proposed in the past. In standard slice based navigation, three dimensional imaging data is visualized on a two dimensional user interface in the surgery room. Another technology is the in-situ visualization i.e. the superimposition of imaging data directly into the view of the surgeon, spatially registered with the patient. Thus, the three dimensional information is represented on a three dimensional interface. We created a hybrid navigation interface combining an augmented reality visualization system, which is based on a stereoscopic head mounted display, with a standard two dimensional navigation interface. Using an experimental setup, trauma surgeons performed a drilling task using the standard slice based navigation system, different visualization modes of an augmented reality system, and the combination of both. The integration of a standard slice based navigation interface into an augmented reality visualization overcomes the shortcomings of both systems.
过去人们提出了几种用于术中导航系统的可视化方法。在基于标准切片的导航中，三维成像数据在手术室的二维用户界面上可视化。另一种技术是原位可视化，即将成像数据直接叠加到外科医生的视野中，并与患者进行空间配准。因此，三维信息在三维界面上呈现。我们创建了一个混合导航界面，将基于立体头戴式显示器的增强现实可视化系统与标准二维导航界面相结合。通过实验设置，创伤外科医生使用基于标准切片的导航系统、增强现实系统的不同可视化模式以及两者的组合来执行钻孔任务。将基于标准切片的导航界面集成到增强现实可视化中克服了这两种系统的缺点。
