International Short Course on Advanced High-resolution 3D Imaging

Target group

This Short Course aims at providing a thorough insight in the working principles, theoretical background and technical aspects of advanced radiation-based 3D imaging techniques related to X-ray µCT, as well as providing an understanding of the differences, advantages and limitations of different techniques.  
The course targets PhD students that specialize in 3D imaging techniques and want to obtain deeper insight in related research fields. Nonetheless, the course is open to post-doctoral researchers as well.
In the Ghent University Doctoral Schools program, this course is complementary to the course “High-resolution X-ray tomography: a guide to image acquisition, processing and visualization”, organized by UGCT in January 2017.  Attendance of this earlier course is not a prerequisite towards enjoying this course.

Content of the course

The course intends to give to the attendees a solid background of different advanced 3D imaging techniques which are often complementary to X-ray μCT. Apart from technical talks on ptychography, grating-based phase contrast, synchrotron X-ray imaging, neutron imaging and diffraction-based imaging, the course will also include talks about data processing, going more into detail about advanced reconstruction methods and data analysis.

Dates and Venue

  • Dates: 17-18-19 January 2018
  • Location: Department of Physics and Astronomy; Proeftuinstraat 86, 9000 Gent

Programme

  • Day 1:  Wednesday 17 January 2018 from 12:00 - 19:00

After lunch and a welcome from the organizers, an advanced lecture on lab-based imaging is planned, covering specific topics such as detector lag, X-ray tube properties, etc. After a coffee break, the mathematics behind tomographic reconstruction will be elaborated, as variations on these methods will be shown in the techniques presented later on. After this, there will be a poster session with ice breaker reception. All attendees will have the opportunity to bring a poster presenting their research topic, providing a good opportunity to get to know each other. A prize will be given to the best poster.
