| Summary: | General principles of 3D reconstruction are composed of two steps. Firstly, the captured successive 2D image slices are arranged precisely with real spatial positions, resulting in volumetric data. This will be followed by ray casted volume rendering techniques, hybrid with semi-auto 3D segmentation and interactive virtual slider for 3D NT measurements. The methodology entails the composite function to visualize the explicit internal marker structure. 3D image diffusion is utilized as preprocessing technique before segmentation, 3D seeded growing is utilized to segment the 3D NT structure followed by its interactive measurement. Details of numerical measurement analysis shall be discussed in Chap. 4. This chapter describes the experimental design and implementation which includes research materials, data sources acquisitions and manipulation, 3D reconstruction and scanning techniques, volume rendering visualization techniques, 3D image preprocessing diffusion, semi-automated 3D segmentation designs, virtual extraction, hybrid visualization and interactive measurements. |
