Dear all We are happy to announce that PETRIC 2 will start in November 2025! >From 1 November 2025 to 1 March 2026, we will be running our second PET Rapid Image reconstruction Challenge. What's this about? - Develop a PET reconstruction algorithm to solve a maximum a-posteriori estimate (MAP) using the smoothed relative difference prior (RDP) - Phantom data with low count levels from different scanners are available for development - An example repository on GitHub with an implementation of a reference algorithm will be provided - Make sure your algorithm is the fastest to reach our target image quality - Win cash prizes Some more details are at https://github.com/SyneRBI/PETRIC2 (more to follow soon). You have not heard about PETRIC before? Have a look here: https://www.ccpsynerbi.ac.uk/petric/ where you can find links to the software, results, awards and the associated workshop, including recordings. PETRIC2 participants will be encouraged to our *special issue* on Rapid Image Reconstruction <https://www.frontiersin.org/research-topics/68511/rapid-image-reconstruction> in Frontiers in Nuclear Medicine. This special issue is *open for everyone until June 2026*, and is not restricted to PET. Please note that we have vouchers available for Open Access fees for submission before September 2025. Feel free to forward this message. We gratefully acknowledge funding from UKRI EPSRC and DRI as well as CoSeC <https://www.cosec.ac.uk/> technical support to be able to run this challenge. On behalf of the PETRIC2 organisers: Charalampos Tsoumpas (RU Groningen), Christoph Kolbitsch (PTB), Matthias Ehrhardt (U Bath), Kris Thielemans (UCL) and CCP SyneRBI <https://www.ccpsynerbi.ac.uk/>.
