【matlab】 Desktop DL : 0: 1917年澳大利亚数学家Radon首先论证了通过物体某一平面的投影重建物体该平面两维空间分布的公式。他的公式要求获得沿该平面所有可能的直线的全部投影(无限集合)。所获得的投影集称为Radon变换。(In 1917, Australian mathematician Radon first demonstrated the formula for reconstructing the two dimensional spatial distribution of an object through the projection of a plane of an object. His formula requires the full projection (infinite set) of all possible lines along the plane. The resulting projection set is called the Radon transform.)

【Graph program】 ctRecontruction DL : 0: 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.)
