You have requested a machine translation of selected content from our databases. Computer Aided Surg 15(1–3):1–12. Because the size of the MSI is too small to do the experiment, only the TSI is done for this test. The marker pairs at the same location in the left and right images must be matched before 3-D reconstruction. Framework of optical tracking system. Through the pre-experiment, the MAR is set as: [11,74] if the area of a highlighted region is less than 11, it is considered to be a noise. With an optical tracking system, it is difficult to match the markers in a traditional way. The real-time synchronization needs to be further optimized to achieve higher system accuracy. Optical Biometer . To achieve high accuracy during measurement in orthognathic maxillary surgery, we introduced a third-generation optical tracking system.

In the space location algorithm, the RG method is designed to find the highlighted connected region of markers in the image. Since the absolute coordinates obtained by the optical tracking system are in the WCS, it is difficult to directly evaluate the accuracy of the world coordinates. Most current computer aided surgery systems are based on localizer technologies. Next, the markers’ extraction, markers’ matching, distortion correction, and 3-D coordinates’ reconstruction procedures are applied to calculate the world coordinates of markers. Optical tracking identifies the pose of a tracked object by measuring light that is either transmitted or reflected by this object. The accuracy of the system is measured by a space distance experiment. 17. Assuming n images are obtained by rotating the surgical instrument, the coordinate of the i’th marker and in the j’th image in the WCS is defined as Pij(Xij,Yij,Zij) (i=1,2,3;j=1,2,…,n). While some application examples have traditionally been addressed by either optical measurement or electromagnetic tracking, due to continual research and development advancements, new opportunities exist with both 3D tracking technologies. The splenic artery, splenic vein, and pancreas were fused onto laparoscopic live images. The brand of grating ruler is SION, and the model is KA-300/5U/1020 mm.
