In the field of modern medical teaching, the use of Computed Tomography (CT), Magnetic Resonance Imaging (MRI) and other equipment to obtain is a two-dimensional image sequence [1], which is not intuitive enough and makes the images difficult to understand. In order to solve the deficiencies in the video teaching method of slides and textbooks, to improve the quality of teaching and the practical ability of students, this paper implements a 3D visualization system based on VTK (visualization toolkit) for medical assistant teaching. This system uses the VTK toolkit. The three-dimensional reconstruction algorithm reconstructs the two-dimensional tomographic sequence of the organ into a three-dimensional organ, visualizes the reconstructed three-dimensional model in the Unity3D engine. The teaching module synchronizes the scene resources to other clients for teaching. Realize the playback of teaching content based on frame synchronization. The collaborative simulation surgery module uses VR (Virtual Reality) equipment to conduct collaborative simulation training, record the training situation in real time and summarize it after the end, so as to facilitate the identification of deficiencies in the task.
