In this paper , a missing data rotative reconstruction algorithms based on rough theory is proposed , and the complexity of the algorithms is analyzed , finally a missing data reconstruction experiment with a typical dataset is conducted 摘要提出了一种基于粗糙集理论的缺失数据循环搜索重建算法,分析了算法的复杂性,并选择一个典型数据集进行了缺失数据重建的实验。
At present , most of the ict systems adopt fbp algorithm which need complete projections of data . in fact , complete projections of data is difficult or even impossible to acquire in many occasions . in this situation , the fbp algorithm is useless 现阶段可实用的ict系统多采用完全投影数据重建的滤波反投影( fbp )算法,而实际中由于客观原因无法检测或很难检测到完全的投影数据,该算法将无能为力。
This paper discusses such a system called ictips ( ict image processing system ) , which is used as software to reconstruct image from tomographic projection data , then make analysis and process the image , obtaining detail information about object being scanned 《工业ct图像重建与处理系统》 ( ictips )是与工业ct设备相配套的软件系统,要完成的功能是将投影数据重建成断面图像然后加以分析处理,得到工件的具体信息。
In order to improve the quality of reconstruction image and solve the problem that " salt and pepper " phenomena occurs in the reconstruction image , the paper proposes a novel algorithm reconstruction technique ( art ) , compare the theory and capability of between them 论文提出新的代数迭代重建算法( art ) ,并且比较了新的重建算法和原有的迭代重建算法的原理和性能,重点研究了在不完全数据重建时, art型算法的性能。
The computer aided medical image 3 - d - reconstruction technologies - - medical visualization 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 计算机辅助的医学图象三维重建技术? ?医学可视化是科学计算可视化的一个具体应用,也是科学计算可视化的最活跃的领域之一,它运用计算机图形学和图象处理技术将来源于ct 、 mri 、生物组织切片等医学二维图象数据重建成三维图象,在屏幕上显示出来并可以进行交互处理。
