Abstract：
Objective The aim of this work was the development of an augmented reality system including the functionality of conventional surgical navigation systems. Methods An application software for the Augmented Reality System HoloLens 2 from Microsoft was developed. It detects the position of the patient as well as position of surgical instruments in real time and displays it within the two-dimensional (2D) magnetic resonance imaging or computed tomography (CT) images. The surgical pointer instrument, including a pattern that is recognized by the HoloLens 2 sensors, was created with three-dimensional (3D) printing. The technical concept was demonstrated at a cadaver skull to identify anatomical landmarks. Results With the help of the HoloLens 2 and its sensors, the real-time position of the surgical pointer instrument could be shown. The position of the 3D-printed pointer with colored pattern could be recognized within 2D-CT images when stationary and in motion at a cadaver skull. Feasibility could be demonstrated for the clinical application of transsphenoidal pituitary surgery. Conclusion The HoloLens 2 has a high potential for use as a surgical navigation system. With subsequent studies, a further accuracy evaluation will be performed receiving valid data for comparison with conventional surgical navigation systems. In addition to transsphenoidal pituitary surgery, it could be also applied for other surgical disciplines.
摘要：
目的这项工作的目的是开发包括常规手术导航系统功能的增强现实系统。方法开发微软增强现实系统HoloLens2应用软件。它实时检测患者的位置以及手术器械的位置，并将其显示在二维（2D）磁共振成像或计算机断层扫描（CT）图像中。手术指针式仪器，包括由HoloLens2传感器识别的图案，是用三维(3D)打印创建的。在尸体头骨上演示了技术概念，以识别解剖标志。结果借助HoloLens2及其传感器,可以显示手术指针式器械的实时位置。当在尸体头骨处静止和运动时，可以在2D-CT图像中识别具有彩色图案的3D打印指针的位置。经蝶入路垂体手术的临床应用具有一定的可行性。结论HoloLens2具有很高的手术导航系统潜力。在随后的研究中,将进行进一步的准确性评估，以接收有效数据与常规手术导航系统进行比较。除了经蝶窦垂体手术,它也可以应用于其他外科学科。
