本文研制了一种实时三维手术导航系统，它将真实的、直观的三维图像叠加在一起，用于医疗诊断和手术。该系统基于积分摄影（IP）原理生成三维图像，称为积分摄像（IV），它不需要任何特殊设备就能显示几何精确的三维图像并再现运动视差。通过半镀银的镜子将三维图像叠加在患者的手术区域上，就好像可以通过身体看到它们一样。此外，一个实时IV算法，用于计算的3-D图像的手术器械被用于注册之间的位置手术器械和器官在手术过程中。通过定点定位和避开关键区域的实验结果表明，该导航系统的定位误差在2~ 3 mm范围内。通过引入具有更高像素密度的显示设备，可以提高系统的精度。
A real-time 3-D surgical navigation system that superimposes the real, intuitive 3-D image for medical diagnosis and operation was developed in this paper. This system creates 3-D image based on the principle of integral photography (IP), named “Integral Videography (IV)”, which can display geometrically accurate 3-D image and reproduce motion parallax without any need of special devices. 3-D image was superimposed on the surgical fields in the patient via a half-silvered mirror as if they could be seen through the body. In addition, a real-time IV algorithm for calculating the 3-D image of surgical instruments was used for registration between the location of surgical instruments and the organ during the operation. The experimental results of puncturing a point location and avoiding critical area showed the errors of this navigation system were in the range of 2~3mm. By introducing a display device with higher pixel density, accuracy of the system can be improved.
