Summary
Surgical Anatomical Structure Transparentization (SAST) uses near-infrared fluorescence imaging to visualize deep anatomy in real-time. This novel approach enhances surgical precision by enabling surgeons to "see through tissue" for improved navigation.
Area of Science:
- Biomedical Engineering
- Surgical Technology
- Medical Imaging
Background:
- Current soft tissue surgery lacks real-time, depth-resolved visualization.
- Preoperative images are inaccurate due to intraoperative tissue deformation.
- Existing navigation tools lack intuitive spatial understanding.
