In this study, a human proximal femur was modeled using these devices, and the matching accuracy thereof is presented. The human proximal femur was modeled by scanning with Breuckmann optical scanning, Metris laser scanning and CT devices. The 3D/3D registration method was performed in two ways: coordinate to coordinate based, and 2D contour based matching. Matching accuracies of the three models were developed with statistical deviation and local deviation. To determine the significance value between the deviations obtained, one way ANOVA, and for intragroup comparisons Tukey and Thamhane tests were used. After statistical analysis, stresses on the models were evaluated using ANSYS software taking Z-VAD-FMK in vivo boundary conditions on human standing position into consideration. In this study, the value of the 2D contour based accuracy deviation of the femur head zone between CT and Metris models was obtained as 0.4?��?0.2?mm while it was 0.3?��?0.1?mm between CT and Breuckmann. The highest matching deviation obtained as a result of the ANOVA test among these three models was found in the femur trochanter region (0.0142?��?0.0164?mm), the lowest value was found in the femur head region (0.0070?��?0.0132?mm). The stress of the CT�CBreuckmann pair was found close to each other in stress analysis. The deviation values obtained by matching models created RhoC by three different methods showed statistically significant results (P?selleck chemicals Values obtained from the CT�CBreuckmann model were lower than those obtained from CT�CMetris. In order to lower deviation values, applications such as increasing the resolution of images, using stronger algorithms, meshing methods and enhancing surface form should be implemented.

However, directly imposing a number of position constraints due to contact with a tool is non-trivial since it is an over-determined problem. This paper extends the FFD to directly impose a number of position constraints for the objects to be embedded in (rounded) cylindrical lattice structures. The position constraints are applied by enabling each surface point to locally deform along the near-normal direction to the surface. The computational time of the local deformation is independent of the number of constrained points other than finite element method. As a real-time application, the proposed method is applied to colonoscopic polypectomy simulation running at over 60?Hz. The proposed method allows efficient simulation of the global and local deformations of complex geometric objects while achieving accurate tool�Ctissue interaction in a realistic and robust manner.
