基于感兴趣区域的精细快速重建
The Rapid and High Resolution Reconstruction Based on Intersted Region
摘要
Abstract
All the existing industrial CT reconstruction algorithm are the tomography of global obj ect, even if you only need to reconstruct a relatively small area of the obj ect,you have to obtain the proj ec-tion data by scanning the fault of the whole obj ect and use the proj ection data to reconstruct the whole obj ect.The data volume is large and it takes a long time by using the iterative methods to reconstruct and it's hard to meet the needs of engineering.The paper intended to have a rapid and low resolution to the entire solid rocket engine,visually select the region of interested,finally use iterative method of high resolution reconstruction to rebuild the region of interested,the method realize the rapid and precisely reconstruction for the defect area in industrial CT.关键词
