A 4D Representation for Training-Free Agentic Reasoning from Monocular Laparoscopic Video
Maximilian Fehrentz, Nicolas Stellwag, Robert Wiebe +7
Spatiotemporal reasoning is a fundamental capability for artificial intelligence (AI) in soft tissue surgery, paving the way for intelligent assistive systems and autonomous roboti…
BridgeSplat: Bidirectionally Coupled CT and Non-Rigid Gaussian Splatting for Deformable Intraoperative Surgical Navigation
Maximilian Fehrentz, Alexander Winkler, Thomas Heiliger +3
We introduce BridgeSplat, a novel approach for deformable surgical navigation that couples intraoperative 3D reconstruction with preoperative CT data to bridge the gap between surg…
TrackOR: Towards Personalized Intelligent Operating Rooms Through Robust Tracking
Tony Danjun Wang, Christian Heiliger, Nassir Navab +1
Providing intelligent support to surgical teams is a key frontier in automated surgical scene understanding, with the long-term goal of improving patient outcomes. Developing perso…
Recognizing Surgical Phases Anywhere: Few-Shot Test-time Adaptation and Task-graph Guided Refinement
Kun Yuan, Tingxuan Chen, Shi Li +9
The complexity and diversity of surgical workflows, driven by heterogeneous operating room settings, institutional protocols, and anatomical variability, present a significant chal…
Beyond Role-Based Surgical Domain Modeling: Generalizable Re-Identification in the Operating Room
Tony Danjun Wang, Lennart Bastian, Tobias Czempiel +2
Surgical domain models improve workflow optimization through automated predictions of each staff member's surgical role. However, mounting evidence indicates that team familiarity…
