Abstract:

BACKGROUND: VTK is a free but professional development platform for images three-dimensional (3D) reconstruction and processing. It is powerful, open-source, and users can customize their own needs by self-development of great flexibility.
OBJECTIVE: To introduce the mostly used Surface Rendering and Volume Rendering technology in images 3D reconstruction, and their typical Marching Cubes and Ray Casting algorithms, and to investigate some applications and extensions on the reconstructed 3D medical images.
METHODS: Based on the free VTK visualization development platform and Visual C++ 6.0 IDE development tools, through C++ language, using real people’s CT dataset, we realized the images 3D reconstruction and also its applications and extensions correspondingly.
RESULTS AND CONCLUSION: Based on the VTK platform, through Surface Rendering and Volume Rendering methods, we realized medical images 3D visualization. The display effect of the reconstructed 3D image is well and intuitive. With the related operations such as measurement, virtual cutting and so on, the good results we desired could be achieved.
