Usage

• Examples of how to use the package are in the examples folder of Algotom. They cover most of use-cases which users can adapt to process their own data.

• Real tomographic data for testing methods can be downloaded from zenodo.

• Methods can also be tested using simulation data as shown in “examples/example_08*.py”

• Users can use Algotom to re-process some old data collected at synchrotron facilities suffering from:

  • Various types of ring artifacts.

  • Cupping artifacts (also known as beam hardening artifacts) which are caused by using: FFT-based reconstruction methods without proper padding; polychromatic X-ray sources; or low-dynamic-range detectors to record high-dynamic-range projection-images.

Methods distributed in Algotom can run on a normal computer which enable users to process these data locally.

• There are tools and methods users can use to customize their own algorithms:

  • Methods to transform images back-and-forth between the polar coordinate system and the Cartesian coordinate system.

  • Methods to separate stripe artifacts.

  • Methods to transform back-and-forth between reconstruction images and sinogram images.
