Beyond excited to share our preprint VesselGraph on Whole Brain Vessel Graphs: A Dataset and Benchmark for Graph Learning and Neuroscience in collaboration with @erturklab @guennemann @DQBM_uzh @UZH_en @TU_Muenchen link: arxiv.org/abs/2108.13233 git: github.com/jocpae/VesselG…

🎉 Excited to announce the #MICCAI2025 SELMA3D 2025 challenge on SSL for 3D light-sheet microscopy segmentation! This year, we are introducing an even larger, more diverse dataset of 3D light-sheet microscopy images 👉 Learn more and join us: selma3d2025.grand-challenge.org

🏥 WCM #Radiology welcomed Johannes C. Paetzold, Ph.D., (@jocpae) earlier this year. Dr. Paetzold is developing interpretable, interactive deep-learning methods that integrate multimodal data—tools clinicians can trust and employ effectively. Read more 👉 tinyurl.com/45v3883h

11/n Formally, #Topograph provides stricter topological guarantees than existing methods. And, we propose a segmentation metric (DIU) capturing fine topological discrepancies that are not captured by existing metrics. 📄 arxiv.org/pdf/2411.03228 💻 github.com/AlexanderHBerg…

10/n Conclusion: We propose a framework for segmentation to identify topologically critical regions via a component graph. Our proposed loss function improves topological accuracy over pixel-wise losses, consistently delivers state-of-the-art performance and is low in runtime.

Excited to share that our paper is accepted at #ICLR2025! We present a topological loss for image segmentation that operates in #graph space. It ensures topological accuracy and computational efficiency. #topology #cv #segmentation with @DanielRueckert openreview.net/forum?id=Q0zmm…

Our new study shows that SARS-CoV-2 spike protein accumulates & persists in the body for years after infection, especially in the skull-meninges-brain axis, potentially driving long COVID. mRNA vaccines help but cannot stop it🔬🧠🦠🧵👇@cellhostmicrobe cell.com/cell-host-micr…
