Table 1 Benchmarking the fast radon transform algorithm implemented at the Lunarc GPU cluster

From: The MAX IV imaging concept

Method 1024 2048
LP/GPU 1.2 10−2 4.5 10−2
FBP (ASTRA)/GPU 4.3 10−2 2.8 10−1
LP/CPU 1.1 10−1 4 10−1
IRT/CPU 1.7 1.2 101
  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)
