  1. The data are taken from [20] where the authors compared among others the following four methods: LP Log-Polar Radon transform and backprojection developed by the authors, FBP as implemented in the Astra toolbox [19], IRT Image Reconstruction Toolbox [22]
  2. Each algorithm is evaluated for the image size of 1024 and 2048 pixels (values represent computational time in seconds)
