  • FDKReconstruction.m and FDKReconstruction.py compute FDK reconstructions for data from a single source-detector orbit, which leads to high cone angle artifacts.
  • GroundTruthReconstruction.m and GroundTruthReconstruction.py compute an iterative reconstructions using the data from all three source-detector orbits, which leads to a reconstruction free of high cone angle artifacts.
  • The complete data set can be found via the following links: 1-8, 9-16, 17-24, 25-32, 33-37, 38-42.

Requirements

  • To use the scrips, you will either need the the ASTRA toolbox more recent than v2.1 or it's development version more recent than 1.9.0dev. If you are using conda, the latter is available through the astra-toolbox/label/dev channel.
  • GroundTruthReconstruction.m makes use of the SPOT toolbox.
