This paper presents an approach to reconstruct instruments with marks. Based on the traditional 3-D reconstruction of single point, we propose a method that reconstructing the marks of the surgery instruments collectively to gain a high positioning accuracy. We match the 2-D projection points, by which the traditional 3-D reconstruction method is used to obtain a rough estimation of the marks' 3-D...
This paper investigates the effect of fiducials configuration on target registration error (TRE) and test the accuracy of theoretical model of TRE prediction in image-guided cranio-maxillofacial surgery. The skull specimen is prepared with 20 titanium microscrews placed at defined locations and scanned with a 64-slice spiral computed tomography unit. These markers are separated to registration fiducial...
According to complementary strategy, this paper presents a new power transformer fault diagnosis method based on rough sets theory (RST)and improved artificial immune network classification algorithm. Through reduction approach of RST information table to simplify expert knowledge and reduce fault symptoms, the minimal diagnostic rules can be obtained. An improved artificial immune network classification...
