摘要: 该论文主要研究在平面情形下指数型 Radon 变换的连续性,得到了它的近似反演公式,并对近似反演的数值解法加以改进.借助一些技巧,该文从理论上还建立了精确反演公式,从而推广了古典 Radon 变换的相应结果.

关键词: 古典Radon变换, 指数型Radon变换, 精确反演, 近似数值反演

Abstract: In this paper, the continuity for the exponential Radon transform in R2 is discussed and the approximate inversion formula is developed. The numerical solution of approximate inversion is also improved. For the sake of theory, the exact form of inverse transform of the exponential Radon transform is given by means of some techniques.

Key words: Radon transform, Exponential Radon transform, Inversion formula, Approximate numerical inversion.
