Code Sprint 2020

Benchmarking Deep Learning based CT Image Reconstruction Methods

Learned reconstruction is becoming more and more important for imaging tasks like computed tomography (CT) reconstruction. In this Code Sprint, we invite researchers and software developers to exchange knowledge, write code, form new collaborations and connect with industrial partners. As a concrete goal, we want to compare the performance of learned reconstruction methods in a challenge setup based on a medical and/or an industrial testing CT dataset.

The sprint was held on June 15–24, 2020 as a virtual event (due to the Covid-19 pandemic). In addition, we would like to organize a physical follow-up meeting in Bremen when the situation will allow it.


The challenges (LoDoPaB-CT, Apples-CT) will be open until end of August. If you would like to join, please still register as a participant.


We were happy to have talks by the following speakers:

  • Prof. Dr. Peter Maass (University of Bremen, Germany)
    Deep learning for CT image reconstruction

  • Dr. Tatiana Bubba (University of Helsinki, Finland)
    Deep neural networks for inverse problems with pseudodifferential operators: the case of limited angle tomography
    Video, Slides, Paper

  • Dr. Anna Trull (GREEFA b.v., Tricht, the Netherlands)
    Deep learning & CT for fruit sorting and quality control

  • Dr. Christian Etmann (University of Cambridge, UK)
    iUNets: Fully-invertible U-Nets for Memory-Constrained Applications
    Video, Slides, Paper
