Human Three-dimensional Reconstruction Of Key Technology Research

The Computer aided medical image 3-D-Reconstruction technologies--MedicalVisualization is one of the most active fields of Scientific Visualization. It reconstruct 3D-Regular Data Sets conies from the CT, MRI or Slice to 3D-Image which can be viewed interactively on the screen. The technologies has a great significant in medical teaching, medical diagnosis N therapy planning and Telemedicine.Medical Visualization is a course of visualization of SD-Regular Data Sets. There are two different visualization approaches of 3D-Data Sets, one is Surface Rendering algorithm, the other is Volume Rendering algorithm. The latter is the emphasis of the paper. The paper describes its optical modeK algorithm classification and discusses its future applications and problems to besolved.A visualization systems based on volume rendering algorithm is introduced at the end of the paper. It has the function to reconstruct 3D-images from 3D-regular data sets and has fine interactive capability.
