Adaptive Video Overlay for Surgical Fluorescence Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video display systems for surgical procedures using endoscopes often obscure anatomical features when overlaying fluorescent light images, making it difficult for surgeons to accurately locate and maneuver tools within the surgical site.
Innovation Solution
A video display system that overlays a fluorescent light video image within a smaller predetermined area surrounded by a white light video image boundary, allowing adjustable size and transparency, and includes an image processor to detect and center tools, enabling surgeons to maintain anatomical references during procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fluorescent light video image is overlaid on the entire white light video image, then tissue perfusion and lesions become more visible, but anatomical features are obscured
Solution Approach 1:
The display area is segmented into two distinct regions: a first display area showing the fluorescent light video image for tissue perfusion and lesion detection, and a second display area showing the white light video image for anatomical feature reference. This spatial segmentation allows both types of information to be simultaneously visible without mutual obscuration.
Solution Approach 2:
The solution transitions from a single-layer overlay approach to a multi-dimensional display arrangement by placing the fluorescent and white light video images in separate spatial dimensions (side-by-side or adjacent regions). This dimensional reorganization preserves all information from both imaging modalities simultaneously.
2Reliability
If the fluorescent light video image covers the entire field of view, then tissue visualization is improved, but tool location and maneuvering become difficult
Solution Approach 1:
The display is segmented to provide dedicated regions for tissue visualization (fluorescent image) and tool positioning reference (white light image with anatomical features). This segmentation enables surgeons to simultaneously access both types of information without switching views, improving both tissue visualization and tool positioning accuracy.
3Device complexity
If a fixed overlay configuration is used, then system complexity is reduced, but adaptability to different surgical preferences is limited
Solution Approach 1:
The display system incorporates dynamic adjustability where the size, shape, and position of the first display area (fluorescent image) can be modified according to surgical needs. This dynamic configuration allows the system to adapt to different surgeon preferences and procedural requirements while maintaining a relatively simple overall structure.

Function Achieved in This Case
Enhances surgical precision by providing clear anatomical features and customizable video displays that help surgeons accurately position tools and visualize tissue perfusion and lesions, improving surgical site visualization and tool placement.
Implementation Method 1
a second video image which displays the surgical site using emitted fluorescent light, for example when using a fluorescing dye such as indocyanine green (ICG) with an excitation light such as near-infrared light (NIR)

AI summary
The present disclosure is directed towards a video display system and an endoscopic system configured to provide the surgeon with an optimized video image based upon user preference. The video display system includes a first video image displaying a white light video of a surgical site. The first video image has a first predetermined area. A second video image is overlaid on the first video image. The second video image is displayed in a fluorescent light video. The second video image is centered on the surgical site and includes a second predetermined area. The second predetermined area is smaller than the first predetermined area so as to define a boundary of white light video. Thus, the video display system provides the surgeon with the ability to reference the location of the fluorescent light video with respect to anatomical features of the surgical site.
