Abstract
In this paper, we successfully extend Natterer’s results to the attenuated Radon transform with imaginary coefficients. And by means of the theory of complex analysis and integral transform, we study the inversion of two-dimensional weighted Radon transform and derive similar explicit inversion formulas with two different methods, which are closely related to Novikov’s inversion formula.
