Tomographic Reconstructions and their Startling Applications

The aim of this workshop is to bring together experts from mathematics, physics, biology, and medicine in fields where tomographic reconstruction methods are applied.

Examples range

  • from analysing astronomical data recorded by huge telescopes, where only very limited angle information is available and refined adaptive optics techniques are used to remove distortions from the atmosphere,
  • over different variants of exploring wave phenomena in biological samples (such as computer tomography, sonography, optical coherence tomography, photoacoustic imaging, elastography, or magnetic resonance imaging to name just a few), where typically a full quantitative reconstruction of the analysed sample would be desirable,
  • down to microscopical scales studied by methods such as stochastic super-resolution microscopy, where localisations of blinking fluorescent molecules below the diffraction limit are realised by giving up on the unique identifiability of the different molecules, or cryogenic electron microscopy, where precise projection images are taken, but without knowing the orientation of the object.

With the interdisciplinary character of this workshop, we not only hope to picture the broad range from theory to experiment and applications, but also hope to see the advantages and disadvantages of the different approaches under a wide variety of aspects, which hopefully stimulates ideas on how to transfer and adapt well working methods to other settings.


The workshop will focus

  • in the first week (from March 15 until March 19) on the mathematical problems such as
    • mathematical modelling of the experiments,
    • reconstructions from tomographic data,
    • scattering and inverse scattering problems, and
    • ill-posedness of the inversions and regularisation techniques;
  • in the second week (from March 22 until March 26) on the experimental challenges in applications such as
    • adaptive optics,
    • elastography,
    • optical coherence tomography,
    • optical tomography of trapped particles,
    • photoacoustic tomography, and
    • superresolution microscopy.


The workshop is organized within the special research programme SFB F68 “Tomography Across the Scales”.

Due to the current situation, the event will be held in a hybrid format, meaning that also a participation via video conference is possible.

Main organizer and contact person for the workshop: Peter Elbau,
