Dense Endoluminal Mapping and Localisation from Monocular Bronchoscopy
Salvatore Esposito, Matias Mattamala, Daniel Rebain +4
Bronchoscopy inserts a camera through the airways to diagnose endoluminal disease. Locating the camera along the airway usually requires additional equipment, such as an electromag…
ROOM: A Physics-Based Continuum Robot Simulator for Photorealistic Medical Datasets Generation
Salvatore Esposito, Matías Mattamala, Daniel Rebain +4
Continuum robots are advancing bronchoscopy procedures by accessing complex lung airways and enabling targeted interventions. However, their development is limited by the lack of r…
VesselSDF: Distance Field Priors for Vascular Network Reconstruction
Salvatore Esposito, Daniel Rebain, Arno Onken +2
Accurate segmentation of vascular networks from sparse CT scan slices remains a significant challenge in medical imaging, particularly due to the thin, branching nature of vessels…
CrossSDF: 3D Reconstruction of Thin Structures From Cross-Sections
Thomas Walker, Salvatore Esposito, Daniel Rebain +4
Reconstructing complex structures from planar cross-sections is a challenging problem, with wide-reaching applications in medical imaging, manufacturing, and topography. Out-of-the…
GeoGen: Geometry-Aware Generative Modeling via Signed Distance Functions
Salvatore Esposito, Qingshan Xu, Kacper Kania +6
We introduce a new generative approach for synthesizing 3D geometry and images from single-view collections. Most existing approaches predict volumetric density to render multi-vie…
