X-ray computed tomography in practice I: application of µCT to investigate materials, autumn 2022

ECTS credits:



Course parameters:

Language: English

Level of course: PhD course

Time of year: Autumn 2022

No. of contact hours/hours in total incl. preparation, assignment(s) or the like: 40 (5x8 hours) / 75 (total, including reading material, conducting project and writing report)

Capacity limits: 6 participants


Objectives of the course:

This graduate course is for PhD students, and other researchers if space permits, who wish to use laboratory-based X-ray micro-computed tomography (µCT) in their research. The course provides the student with an introduction to the basics of X-ray CT followed by experimental exercises composed of user training on the X-ray microscope Zeiss Xradia 620 Versa. Furthermore, simple tools for data analysis will be introduced, including computer exercises on the use of these tools for quantification and visualization of CT data. Data from CT measurements of bone, as an example of a material structured over several length scales, will be supplied for these exercises. Finally, each student will have a project day with an expert user to work on their own sample. The resulting data should be visualized and analyzed, and the project described in a report for assessment of the student’s learning outcome. 


Learning outcomes and competences:

At the end of the course, the student should be able to:

- describe the basics of X-ray CT, including experimental concepts and the idea behind filtered back projection for image reconstruction

- conduct a simple X-ray CT experiment

- analyze CT data in terms of simple quantification and visualization

- describe/consider how apply X-ray CT within his/her own research


Compulsory programme:

Participation in all course components, including lectures, experimental, and computer exercises.
