Dear all

The deadline for submitting to PETRIC2 is getting close!  15 February 2026 23:59 (GMT). We do not intend to extend the deadline. If you are participating (you can still sign up!), a few helpful links:

IMPORTANT: we now need "unseen" data to complete the evaluation. If you can contribute, please do so ASAP, see Information for contributors of phantom data for PETRIC2 · SyneRBI/PETRIC2 Wiki<https://github.com/SyneRBI/PETRIC2/wiki/Information-for-contributors-of-phantom-data-for-PETRIC2>.

3 top-scoring teams will be invited to present their work at the Symposium on AI and Reconstruction for Biomedical Imaging<https://www.ccpsynerbi.ac.uk/events/airbi/>. A quick reminder to register for the symposium or the associated hackathons (on STIR and on machine learning approaches for image reconstruction) . 3 separate registrations needed!

We're looking forward to seeing what the teams have (re)constructed for fast and robust algorithms!

On behalf of the PETRIC2 organisers
