Fast Laplace Transforms for the Exponential Radon Transform

Andersson, Fredrik LU ; Carlsson, Marcus LU and Nikitin, Viktor V. LU (2018) In Journal of Fourier Analysis and Applications 24(2). p.431-450
Abstract

The Fourier slice theorem for the standard Radon transform generalizes to a Laplace counterpart when considering the exponential Radon transform. We show how to use this fact in combination with algorithms for the unequally spaced fast Laplace transform to construct fast and accurate methods for computing both the forward exponential Radon transform and the corresponding back-projection operator.
