Abstract

A variety of inversions of the exponential Radon transform have been derived based on the circular harmonic transform in Fourier space by several research groups. In this paper, we derive a Cormack-type inversion of the exponential Radon transform by employing the circular harmonic transform directly in the projection space and in the image space instead of the Fourier space. This solution of the generalized Cormack equation is applicable to theexponential Radon transform with a complex parameter and can be used for reconstruction not only in single-photon emission tomography but also in polarized tomography of stress tensor fields.
