Many thanks to all participants as well as contributors of phantom data, the CoSeC<https://www.cosec.ac.uk/> <https://www.cosec.ac.uk/> team for support and computing resources, and of course UKRI for funding CCP SyneRBI<https://www.ccpsynerbi.ac.uk/>. More details, including links to their contributions, leaderboard etc, are on the PETRIC2 Wiki award page<https://github.com/SyneRBI/PETRIC2/wiki/Awards-and-results>. Recordings of the presentations by the teams will be available later. I will take the opportunity to also make you aware of the recent publication of our paper describing the first PETRIC: C. da Costa-Luis et al., PET rapid image reconstruction challenge (PETRIC)<https://www.frontiersin.org/journals/nuclear-medicine/articles/10.3389/fnume.2026.1770002/full>, Front. Nucl. Med., 27 March 2026 DOI: 10.3389/fnume.2026.1770002<https://doi.org/10.3389/fnume.2026.1770002> And of course, don't forget to spread the word (and participate!) in Big Cross-Modal Attenuation Correction (BIC-MAC) Challenge<https://bic-mac-challenge.github.io/> organised by our colleagues from Rigshospitalet and Technical University of Denmark. On behalf of the PETRIC and PETRIC2 organisers Matthias Ehrhardt (U Bath), Christoph Kolbitsch (PTB), Charalampos Tsoumpas (RU Groningen), Kris Thielemans (UCL) and Casper da Costa-Luis, Edoardo Pasca (CoSeC, UKRI STFC) Kris Thielemans Professor in Medical Imaging Physics at University College London, Institute of Nuclear Medicine, UCL Hospital Tower 5, 235 Euston Road, London NW1 2BU, UK |

Dear STIR community members, We invite you to participate in the Big Cross-Modal Attenuation Correction (BIC-MAC) Challenge, held in conjunction with MICCAI 2026. SyneRBI is an official challenge partner, and several members of the SyneRBI and STIR communities have been major contributors to its design and implementation. There is a prize pool of €1000 EUR, and registration is now open at https://bic-mac-challenge.github.io along with instructions to get started. The Task: The challenge tasks participants with developing a generative AI model to synthesize 3D pseudo-CT images for PET attenuation correction (AC). Possible model inputs include whole-body MRI, non-attenuation-corrected PET (NAC-PET), and/or 2D scan-planning topograms. The target clinical application is CT-less AC for dose-sensitive populations and whole-body PET/MRI. Evaluation via STIR: Submissions are evaluated based on the accuracy of the resulting AC-PET reconstruction, and the reconstruction pipeline is built entirely on STIR. Participants are provided with STIR reconstruction scripts (or Docker container if preferred) to enable model iterations with reconstruction in-the-loop. Note that for this first challenge iteration, the reconstruction logic is fixed, and the submitted generative model must produce only CT images. For a future version of the challenge, participants will be allowed to directly predict the AC-PET, perform joint reconstruction, and more. Datasets: Participants will be given access to a novel 650GB age- and sex-stratified dataset of 79 long axial field of view whole-body cases (75 training, 4 validation), and a test-set of 20 cases is held for final evaluation. The dataset comprises [18F]FDG PET, CT, MRI, and Topograms and the underlying PET sinograms needed for reconstruction. The data was acquired on a Siemens Biograph Vision Quadra (PET/CT) and a Siemens MAGNETOM Vida (MRI) and is the first publicly available human dataset with Quadra sinograms. We hope that you will consider participating in this challenge and spreading the word to colleagues who may be interested. The top five scoring teams will be invited for a joint publication following MICCAI 2026. More information, registration, and resources for getting started at https://bic-mac-challenge.github.io.

Dear all We are very happy to announce that the second version of our PET image reconstruction challenge is now open. You can find all details on the corresponding wiki page at https://github.com/SyneRBI/PETRIC2/wiki. Briefly: * The aim is to develop a fast reconstruction algorithm for a MAP (aka Penalised Likelihood) problem. * Acquired phantom data from several clinical scanners will be used to rank submissions. Data will be considerably noisier (i.e. lower counts) than in PETRIC1. * Participants need to use our Python-based software SIRF<https://github.com/SyneRBI/SIRF/wiki>, STIR<https://github.com/UCL/STIR/wiki> and CIL<https://tomographicimaging.github.io/CIL/>. * Cash prizes, presentations at (and free travel to) our forthcoming Symposium on AI and Reconstruction for Biomedical Imaging<https://www.ccpsynerbi.ac.uk/events/airbi/> and eternal glory are up for grabs! Don't forget that results, algorithms, presentations etc from the first PETRIC are available via https://github.com/SyneRBI/PETRIC/wiki. See also our Special Issue on Rapid Image Reconstruction<https://www.frontiersin.org/research-topics/68511/rapid-image-reconstruction> (Frontiers in Nuclear Medicine), which will remain open for submission for participants of PETRIC2. We will hold an online training session that beginning of December. Check our website<https://www.ccpsynerbi.ac.uk/> and mailing lists for an announcement in the next few days. We hope to see your registration soon! Feel forward this message. On behalf of the PETRIC2 organisers: Matthias Ehrhardt (U Bath), Christoph Kolbitsch (PTB), Charalampos Tsoumpas (RU Groningen), Kris Thielemans (UCL), and CCP SyneRBI<https://www.ccpsynerbi.ac.uk/> (UKRI funding).

Dear all I'm very happy to announce STIR 6.3.0. This version is 100% backwards compatible with STIR 6.2, aside from three important bug fixes, which will change results. This is a release with many new features, as listed below. Highlights are * the new Gibbs penalty hierarchy with CUDA and OpenMP support (and much easier addition of new potential functions) (Matteo Neel Colombo, Univ of Milano-Bicocca), * new 2D analytic reconstruction algorithms (including two that allow quantitative reconstruction of SPECT) (Dimitra Kyriakopoulou, UCL), * better Python support including algebraic operations and faster conversion to NumPy arrays (Kris Thielemans, UCL), * continuous memory storage for arrays (allowing zero-copy access to image/projection data in SIRF Python, but not yet in STIR Python) (Kris Thielemans, UCL), * faster scatter estimation for blocks on cylindrical scanners (Markus Jehl, Positrigo), * reduced memory usage for iterative reconstructions, avoiding hitting the current limitation of 2^31 elements in ProjDataInMemory (Kris Thielemans, UCL), * Python code for adapting e7tools output for Siemens Vision 600 to STIR (Nicole Jurjew, UCL) But there are many other changes from other contributors as well. Of course, there is also the usual code-cleanup and some improvements to the documentation. Overall overview and release management was by Kris Thielemans (UCL) with help from Daniel Deidda (NPL). Full details are in the Release notes for STIR 6.3<https://stir.sourceforge.net/documentation/release_6.3.htm>. Download instructions and others links are at https://stir.sourceforge.net/download/. Many thanks to all STIR contributors for making this release so exciting. I'm looking forward to seeing some of you at our (hybrid) STIR User's and Developer's meeting<https://stir.sourceforge.net/2025UsersMeeting/> next Thursday (see details on the website) to discuss progress and future of STIR!

Dear Fumio I’m answering to the mailing list, in case it helps others. Indeed, STIR Cannot directly read the output of e7tools. One reason is that the header information is incomplete, and in some cases incorrect. For Siemens, this doesn’t matter as they know what the scanner does, but for STIR this is problematic. Luckily, Nicole Jurjew (one of my PhD students) looked at this for the Vision 600 and has constructed a script to process the Vision data. You can find it at STIR/examples/python/Vision_files_preprocess.py at master · UCL/STIR<https://github.com/UCL/STIR/blob/master/examples/python/Vision_files_preprocess.py>. It does need STIR master. I hope to release a new version soon. We are adapting this script to handle Quadra data, and also mCT. Hopefully that should make it possible to work with Truepoint data as well. Best thing to do is to have a look at the script first, and then maybe ask some more questions (please send to the mailing list). Together we can generalise the script. Even better would be to join us at the STIR User’s meeting at the MIC (or virtual), for which you can find info on the STIR website STIR User's and Developer's Meeting 2025<https://stir.sourceforge.net/2025UsersMeeting/>, including a survey to let us know what you’re interested in.

My name is Fumio Hashimoto, a postdoc at Gong Lab (University of Florida). I am currently working on the reconstruction for the Siemens Truepoint scanner using STIR. The sinograms were generated from e7tools, but STIR fails to read them and the reconstruction does not start. I suspect a header mismatch (it seems STIR is inferring TOF bins because STIR read mCT information...?). Could you advise on the recommended way to use these data in STIR?

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.
