PhD Position in Phase Contrast X-ray Computational Imaging

University of Antwerp


PhD student position in Phase Contrast X-ray Computational Imaging (f/m)


The Vision Lab, an imec ( research group at the University of Antwerp ( ), has open positions for PhD students to work advanced image reconstruction methods for X-ray phase contrast tomography. Tomography is an image reconstruction technique that leans strongly on large-scale numerical mathematics, particularly linear algebra. It has a wide range of applications in medicine (CT-scans), industry (nondestructive testing, inspection and quality control) and science (3D characterization and material analysis).

With phase contrast X-ray CT, images can be acquired with unprecedented contrast far surpassing conventional CT contrast. This technique was only available at large-scale synchrotron facilities, but recent developments now allow for low brilliance, polychromatic X‐ray sources in lab CT systems. The PhD students will design phase contrast gratings and develop phase retrieval and image reconstruction algorithms. These algorithms will be used for the analysis of fiber reinforced materials and food in collaboration with industry.


You have a M.Sc. degree in Mathematics, Physics, or Engineering with good programming skills. You love interdisciplinary science, and want to advance the field of dynamic CT with your enthusiasm, creativity and novel solutions. You have a good sense of humor and like to develop theory and afterwards code to put your new methods into practice. You also want to tell the world about your findings with sparkling presentations.

Labs involved:

The Vision Lab, an imec ( research group of the physics department at the University of Antwerp. The Vision Lab has unique expertise in the development of algorithms for reconstruction, processing and analysis of tomographic imaging data. The working environment is strongly interdisciplinary, combining techniques and insights from Physics, Mathematics and Computer Science. The group has a broad range of national and international collaborations with both academic and industrial partners (e.g. AXIM group at UCL, London). Recent publications on tomography can be found on .


Our offer:

  • An exciting research trajectory towards a PhD
  • Multidisciplinary research: cooperation with strong academic research and industrial partners
  • A world-class research environment with state-of-the-art instrumentation and a brand-new customized UniTOM XL microCT system (FlexCT)
  • Salary and beneficials are described here:


Starting date:
