-Medical image visualization technologies build 3D models with 2D medical image series to provide useful and precise information for the doctors. It is one of the crucial technologies in CAS system, Image Guide Surgery and Minimal Invasive Surgery. VTK is an advanced toolkit for the medical 3D visualization. DICOM is the international standards in the medical digital imaging and the data communicating, it unifies the formats of the medical image. In this paper, the VTK data-processing mechanism is outlined firstly, then VTK significant characteristics and common procedures model are introduced　Secondly, the correct interpretation way of the DICOM images is brought forward. Three-dimensional reconstruction of the visual procedures is developed with VC++ and VTK, then implements some functions　Finally, A medical 3D visualization analyzing laboratorial system is developed based on VTK in Windows. The system employs surface rendering and creation of visual slices based on VTK, and offers
