Introduction to X-ray computed tomography

Target Group

Open to any PhD students interested to use Micro-CT in their research. No prerequisites required.


High-resolution X-ray computed tomography (or micro CT) is a non-destructive imaging technique which has gained significant importance in many different research domains in Natural sciences, geology, archaeology, biology, pharma and engineering. The aim of this course is to introduce the technique to any PhD student interested to (or has started to) apply micro-CT in his or her PhD research.

Topic and Objectives

The aim of this course is to introduce the micro-CT technique to the students. The course consists of lectures with basics of X-ray physics, micro-CT, 3D image reconstruction, analysis and hands-on sessions on tomography measurements at the UGCT campus along with 3D image visualization and image analysis. Furthermore, the students can have the opportunity to measure their own samples during the practical sessions upon prior discussion.

Upon completion of this course the students will be familiar with the fundamentals of X-ray interaction with matter, the advantages and limitations of micro-CT and the potential of image processing. The course provides an overview of various applications of micro-CT and different experimental setups that can be combined with the micro-CT techniques at UGCT. Using this facility, the students will be able to optimally design their experiments and analyse their experimental data.
