Endoscopy Panoramic Imaging for Branching-Path Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible medical instruments face challenges in navigating complex branching structures due to limited field of view and obstruction by interior sidewalls, making it difficult to maneuver and visualize the path during procedures like endoscopy.
Innovation Solution
A system that generates panoramic images of the branching structure using a combination of captured images and synthesized views, providing a broader field of view and guidance indicators to assist in navigating through complex anatomical structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a standard camera is used at the distal end of the flexible medical device, then the device structure remains simple, but the field of view is limited and interior sidewalls obstruct the view
Solution Approach 1:
The patent creates a virtual panoramic copy of the branching structure by synthesizing multiple standard camera images into a comprehensive panoramic view. This virtual copy provides the enhanced field of view without requiring physically larger or more complex camera hardware at the distal end of the device.
Solution Approach 2:
The system introduces an image processing intermediary that captures multiple views from the standard camera and synthesizes them into a panoramic image. This intermediary component enables the transition from limited direct camera view to expanded panoramic visualization without changing the fundamental camera hardware.
2Area of stationary object
If multiple cameras are used to expand the field of view, then the visualization coverage improves, but the device complexity and image processing requirements increase
Solution Approach 1:
The patent transitions from a single-point camera view to a multi-dimensional panoramic representation by capturing images at multiple positions along the branching structure and synthesizing them into a comprehensive spatial view that encompasses areas beyond the immediate camera field of view.
Solution Approach 2:
The system performs preliminary image capture and synthesis operations to create panoramic views before the operator needs to navigate complex branching sections. By pre-generating comprehensive visual information, the system reduces the need for real-time complex image processing during critical navigation moments.
3Ease of operation
If the flexible medical device is maneuvered through complex branching structures, then the procedure can be completed, but navigation difficulty increases due to limited visualization
Solution Approach 1:
The system provides continuous feedback by displaying panoramic images that show the current position within the branching structure and the surrounding anatomy. This feedback loop enables operators to make informed navigation decisions by visualizing the spatial context and anticipating upcoming branching points before physically reaching them.
Solution Approach 2:
The patent transforms the limited one-dimensional linear view through the branching structure into a two-dimensional panoramic representation that displays spatial relationships in multiple directions simultaneously. This dimensional transformation enables operators to perceive the three-dimensional anatomy and navigate more effectively through complex branching pathways.
