Besides, we develop a virtual reality navigation system in human body. Users can navigate the human body and get some medical knowledge. 　　In the 3D reconstruction system, we present the organs in the images with the contours. Through the interaction with the users, we reconstruct the 3D objects according to the user judgments. Therefore, users can observe the 3D objects in a more concrete way. In the reconstructive process, we meet some problems such as branching tubes. Therefore, we provide some specific algorithms to solve these problems. 　　Users can use the 3D reconstruction system to read a series of human image files and draw the contours of the organs in the images to reconstruct the 3D objects. Therefore, we can get a complete human model. The data are the input of the navigation system. In the system, users can navigate the human body through some easy operations. Besides, we also provide some medical knowledge such as the 2D cross-sections and the organ information to the users while they are navigating.
