Description: 该附件的函数可实现CT重建的功能,如简单的反投影,在空间域中使用卷积的滤波反投影,采用了二维傅立叶变换的滤波反投影,并利用中心切片定理滤波反投影。
CT技术诞生以来, 人们已经发展了众多的图像重建算法, 但各种算法均存在着各自的优缺点。解析重建(Analytic Reconstruction, AR)和迭代重建(Iterative Reconstruction, IR)是CT图像重建的两种基本方法。滤过反投影(Filtered Back Projection, FBP)是解析重建的主要算法, 代数重建算法(Algebraic Reconstruction Technique, ART)是迭代重建中常用的算法。虽然世界上第一台医用CT就采用ART, 但FBP很快就代替ART成为CT图像重建的“金标准”, 这是由于ART计算速度慢、所需存储空间大, 在计算机技术水平不是很高的年代, 它的应用和发展受到了限制。(CT reconstruction package
Set of functions performing ct reconstruction tasks like a radon transformation, a simple backprojection, a filtered backprojection using a convolution in the spatial domain, a filtered backprojection using a 2D Fourier transformation, and a filtered back projection using the central slice theorem.)
