VISUALIZATION OF THREE-DIMENSIONAL ORGANIC DATA BASED ON CT IMAGE
Discuss how to use the digital image processing technology and realize the visualization of three-dimensional data of tissue and organs. Through internal segmentation and edge detection, the edge extraction and tracking were fulfilled and three-dimensional CT image data was obtained. And based on the characteristics of medical images, the following algorithms were proposed: the minimal diagonal algorithm which solved the big curvature and distortion problem; the dummy point bridge algorithm which solved the branching problem; the transition layer algorithm which solved the holes in skeleton problem. Finally, validate the algorithms through a human ear visualization case, in the same time,three-dimensional data was compressed to solve the data redundancy problem. All these steps ensure the accuracy of visualization and obtaining the satisfying organ images.The visualization result can be further used by CAD and RP system, which produce the prototype of tissue and organs.
