- 这是一个基于扇形束反投影滤波重建的算法，可用于CT重建。-This is a backprojection filtering reconstruction algorithm, based on the fan-beam CT reconstruction can be used.
ctRecontruction
- 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
ctRecontruction
- 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
