Verifying the Accuracy of a Dental Fiberscope Navigation System and Clinical Application

导航系统误差是由3D重建图像、配准误差、位置传感器误差、传感器标记位移和监视器上显示图像的失真引起的。在这段时间里，我们验证了导航的总精度。总准确度定义为监视器上的纤维镜图像与关键图像之间的差异。关键图像是具有已知大小的网格。我们在接骨板和纤维内窥镜头端上做了标记。把堵塞物放在盘子上。将纤维镜连接到三轴试验机上。然后，我们显示了阻塞和纤维内窥镜3D图像。随后对这些图像的坐标进行了登记。纤维内窥镜随网格移动，并记录路径。我们测量了网格坐标和纤维镜尖端坐标之间的差异。我们验证了牙科纤维镜导航系统的总精度和系统上位置的最终精度。

Navigation system error is caused by 3D reconstructed images, registration error, position sensor error, sensor marker displacement, and distortion from displaying the image on the monitor. In this time we verified the total accuracy of the navigation. Total accuracy was defined as the difference between the fiberscope image on the monitor and the critical image. The critical image is a grid that has a known size. We attached a marker to the plate and the tip of the fiberscope. The blockage was put on the plate. The fiberscope was attached to the triaxial tester. We then displayed the blockage and the fiberscope 3D images. The coordinates of these images were subsequently registered. The fiberscope was moved with the grid and the pathway was recorded. We measured the difference between the grid coordinate and the tip of fiberscope coordinate. We verified the total accuracy of the dental fiberscope navigation system and resultant accuracy of the position on the system.
