摘要
Abstract
BACKGROUND: Three-dimensional reconstruction identifies two-dimensional medical images to recover the three-dimensional images of detected tissues and organs.OBJECTIVE: To analyze algorithm choice for medical image 3D reconstruction.METHODS: A computer-based online search of CNKI and Pubmed databases was performed to search related articles with key words "medical image, three-dimensional reconstruction, surface rendering, volume rendering" in Chinese and English. A total of 33 articles regarding algorithm of medical image three-dimensional reconstruction were collected to analyze the implementation principle, complexity, and real-time display of surface rendering technology and volume rendering technology.RESULTS AND CONCLUSION: Medical image three-dimensional reconstruction is classified into surface rendering, volume rendering and combined rendering according to data description methods. Surface rendering exhibits advantages in algorithm efficiency and real time reciprocity compared with volume rendering. Although surface rendering results in detail loss during rendering, it has been extensively applied due to simple operation and small memory occupying. Volume rendering is direct operation on voxel in volume dataset, which can render abundant information of three-dimensional dataset. Therefore, the rendering effect is better than surface rendering.关键词
