Simulation-Based Segmentation of Blood Vessels in Cerebral 3D OCTA Images

no code implementations11 Mar 2024 Bastian Wittmann, Lukas Glandorf, Johannes C. Paetzold, Tamaz Amiranashvili, Thomas Wälchli, Daniel Razansky, Bjoern Menze

Segmentation of blood vessels in murine cerebral 3D OCTA images is foundational for in vivo quantitative analysis of the effects of neurovascular disorders, such as stroke or Alzheimer's, on the vascular network.


Link Prediction for Flow-Driven Spatial Networks

1 code implementation25 Mar 2023 Bastian Wittmann, Johannes C. Paetzold, Chinmay Prabhakar, Daniel Rueckert, Bjoern Menze

In this work, we focus on link prediction for flow-driven spatial networks, which are embedded in a Euclidean space and relate to physical exchange and transportation processes (e. g., blood flow in vessels or traffic flow in road networks).

Focused Decoding Enables 3D Anatomical Detection by Transformers

1 code implementation21 Jul 2022 Bastian Wittmann, Fernando Navarro, Suprosanna Shit, Bjoern Menze

To tackle this issue and facilitate the advent of medical Detection Transformers, we propose a novel Detection Transformer for 3D anatomical structure detection, dubbed Focused Decoder.
