这个周末莫名其妙的开始在YouTube上看介绍computed tomography的算法,便开始看算法,写代码,经过多半天的努力,突然豁然开朗. 对计算机断层扫描算法也有了了解,通过手撸代码实现了computed tomography的功能,并初步了解了Radon transform算法和Reconstruction with the Filtered Back Projection (FBP)算法,当然这个也绕不开傅里...
An iterative algorithm for computed tomography image reconstruction from limited-angle projections In application of tomography imaging, limited-angle problem is a quitepractical and important issue. In this paper, an iterativereprojection-reconstruction... Y Sun,J Tao,C Liu 被引量: 0发表: 2013年 ...
Computed tomography (CT) systems use a series of X-ray images to create an image volume dataset with slices that can be manipulated on any plane using advanced visualization software. The section includes computed tomography scanners, CT contrast agents,

Computed Tomography Image Reconstruction Introduction Computed tomography is a collection of X-ray images stacked together in order to get the depth information as the third dimension of a diagnostic image. These "stacked" X-ray images are received as a sinogram from the CT gantry, and represent ...

The charge coupled device and the acquisition board allows image processing, filtration and restoration. A reconstruction programme, written in PASCAL is able to give the reconstruction matrix of the linear attenuation coefficients, and simulates the matrix and the related tomography. The flux emitted ...
