Research Abstract |
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.
