Based on the Fourier slice theorem used in X-ray tomography and paraxial approximation, an iterative method was developed to eliminate the influence of wavefront curvature on reconstructed images. Computer simulations showed that the quality of reconstructed images was apparently improved by using the method. In comparison with already existing methods, the present method is more practical and can be used for limited angle reflection mode tomographic imaging.
