High-resolution X-ray computed tomography: A guide to image acquisition, visualization and analysis

Target group - Aim and Scope

High-resolution X-ray computed tomography (micro-CT) is an experimental imaging technique that has gained significant importance in many different research domains over the last few years, e.g. geology, archeology, biology, pharma and engineering. This course aims to help students who are interested in using micro-CT in their own research, or who have just started using it, by introducing them to the advantages and the limitations of micro-CT, to the theoretical considerations behind it, and finally to best practices when using this measurement technique. This contains an introduction to the following aspects:

  • X-ray physics and working principles behind micro-CT
  • Hardware en equipment considerations
  • Tomographic reconstruction (processing the raw data)
  • Visualizing and quantitatively analyzing the reconstructed data with specialized software
  • Inspiring examples of use cases, including tips and tricks.


PhD students of the Doctoral Schools of Natural Sciences, (Bioscience) Engineering and Life Sciences and Medicine.
