目的：我们开发了一种重叠三维图像（体积图）引导的导航系统，可以在手术过程中进行导航。三维图像通过半透明镜子叠加在患者的头部和身体上。 Volumegraph可以通过基于CT/MRI的光束在空气中显示三维图像。方法：该系统由Volumegraph（三维记录介质薄板）、Volumegraphscope和原创设计的用于配准的三角形标记系统组成。术前从CT和MRI获得的三维数据经过计算机处理。这些图像数据用于术前检查，以识别器官和肿瘤的三维结构。这些重建的三维图像根据基准标记（配准）叠加并在患者头部配准。然后操作员可以使用该三维图像引导导航系统进行操作。结果：根据 7 例临床应用，发现该系统具有优势，因为手术现场可以通过增强现实轻松导航手术过程。手术区域的不可见部分通过叠加的三维图像（体积图）进行补充，就好像它是虚拟手术区域一样。另一个时候，体积图的空间定位和叠加可视化对于识别图像中的解剖结构和功能位置非常有用。结论：这项重叠三维图像引导导航的初步研究证明了其临床实用性。增强现实在外科领域的应用使得轻松、准确地进行神经外科干预成为可能。
Objective: We have developed an overlaid three-dimensional image (Volumegraph)-guided navigation system that allows navigation during operative procedures. The three-dimensional image is superimposed on the patient's head and body via a semi-transparent mirror. The Volumegraph can display three-dimensional images in the air by a light beam which is based on CT/MRI. Method: The system consists of a Volumegraph (thin plate of three-dimensional recorded medium), a Volumegraphscope and an original designed triangular-shaped marker system for registration. The three-dimensional data obtained from CT and MRI before the operation were processed by a computer. Such image data are applied for preoperative investigation to recognize the three-dimensional structure of organs and tumor. These reconstructed three-dimensional images were superimposed and registered at the patient's head according to a fiducial marker (registration). Then the operator can operate with this three-dimensional-image-guided navigation system. Results: Based on clinical application in 7 cases, the system was found to be advantageous because the surgical procedures could be navigated easily by augmented reality in the surgical field. Invisible parts of the surgical field were supplemented with the overlaid three-dimensional images (Volumegraph) as if it were the virtual operative field. At another time, spatial positioning and overlaid visualization by the Volumegraph was useful for identifying anatomical structures and functional location in the image. Conclusion: This preliminary study of overlaid three-dimensional-image-guided navigation demonstrated its clinical usefulness. The application of augmented reality in the surgical field makes it possible to do a neurosurgical intervention easily and accurately.
