基于术前计算机断层扫描数据，评价三维增强现实系统结合整体摄像用于口腔颌面部区域成像的可行性和准确性。基于计算机断层扫描数据的颌骨的三维表面模型被用于创建受试者的颌面部区域的整体摄像图像。使用三维增强现实系统（集成视频显示器、计算机断层扫描、位置跟踪器和计算机）生成三维覆盖图，通过半镀银镜将其投影到手术部位。此后，对志愿者进行了可行性研究。该系统的准确性进行了验证的实体模型，同时模拟骨切除。通过识别和跟踪患者/手术器械的位置来实现位置配准。因此，颌骨、牙齿和手术工具的完整视频图像叠加在正确的位置。从各个角度观察的立体图像被准确地显示。视角的变化不会对外科医生在没有特殊眼镜的情况下同时观察三维图像和患者的能力产生负面影响。实体模型和增强现实导航上每个测量点的三维位置差异几乎可以忽略不计（<1 mm）;这表明该系统具有高度准确性。这种增强现实系统对于手术导航和将三维计算机断层扫描图像叠加在患者手术区域上具有高度准确性和有效性，使外科医生能够用肉眼了解术前图像和实际手术部位之间的位置关系。
To evaluate the feasibility and accuracy of a three-dimensional augmented reality system incorporating integral videography for imaging oral and maxillofacial regions, based on preoperative computed tomography data. Three-dimensional surface models of the jawbones, based on the computed tomography data, were used to create the integral videography images of a subject's maxillofacial area. The three-dimensional augmented reality system (integral videography display, computed tomography, a position tracker and a computer) was used to generate a three-dimensional overlay that was projected on the surgical site via a half-silvered mirror. Thereafter, a feasibility study was performed on a volunteer. The accuracy of this system was verified on a solid model while simulating bone resection. Positional registration was attained by identifying and tracking the patient/surgical instrument's position. Thus, integral videography images of jawbones, teeth and the surgical tool were superimposed in the correct position. Stereoscopic images viewed from various angles were accurately displayed. Change in the viewing angle did not negatively affect the surgeon's ability to simultaneously observe the three-dimensional images and the patient, without special glasses. The difference in three-dimensional position of each measuring point on the solid model and augmented reality navigation was almost negligible (<1 mm); this indicates that the system was highly accurate. This augmented reality system was highly accurate and effective for surgical navigation and for overlaying a three-dimensional computed tomography image on a patient's surgical area, enabling the surgeon to understand the positional relationship between the preoperative image and the actual surgical site, with the naked eye.
