摘要
本文将对求解Ｒａｄｏｎ变换的改进Ｆｏｕｒｉｅｒ算法进行误差分析，证明了在Ｌ２范数下改进Ｆｏｕｒｉｅｒ算法是收敛的且具有Ｏ（１／ｑ）敛阶，其中２ｑ为像素点矩陈阶数。
In this paper, we will carry out the error analysis of improved Fourier algorithm for solving Radon transform. We prove that the improved Fourier algorithm is convergence under L2 norm with a convergence rater of O(1/q), Where 2q is the order of picture element matrix.
