Procedure-Aware Surgical Video-language Pretraining with Hierarchical Knowledge Augmentation [PDF]
Surgical video-language pretraining (VLP) faces unique challenges due to the knowledge domain gap and the scarcity of multi-modal data. This study aims to bridge the gap by addressing issues regarding textual information loss in surgical lecture videos and the spatial-temporal challenges of surgical VLP. We propose a hierarchical knowledge augmentation

The efficacy of 3D hologram support with mixed‐reality technique in pancreatobiliary endoscopy
Abstract Background and Aims Mixed‐reality (MR) technology is an advanced holographic imaging system that uses wearable devices to display three‐dimensional (3D) images in clinical environments. In pancreatobiliary endoscopy, MR technology can facilitate 3D visualization of the bile and pancreatic ducts, enhancing spatial awareness and providing a more
