Endoscopic ROI Display Control Using Tool-State Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscope systems struggle to provide clear distinguishability of regions of interest during medical procedures, particularly when tools are being used, which can confuse medical professionals and hinder precise interventions.
Innovation Solution
A medical image processing apparatus and method that recognizes tool information from observation images, distinguishing between treatment, pre-treatment, and non-treatment states, and adjusts image display to enhance or reduce distinguishability based on this information, using tools like frames, symbols, and color changes to highlight regions of interest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If tool information recognition and state-based display control are implemented, then the distinguishability of regions of interest is improved, but the device complexity increases
Solution Approach 1:
The patent segments the treatment process into distinct states (non-treatment, pre-treatment, treatment) based on tool information recognition. Each state has specific display control rules applied to the region of interest, allowing complex processing requirements to be divided into manageable state-specific segments that improve distinguishability without overwhelming system complexity
Solution Approach 2:
The patent implements dynamic display control that automatically adjusts the distinguishability of the region of interest based on the recognized treatment state. The display characteristics (such as highlighting, framing, or color coding) are dynamically modified according to whether the system is in non-treatment, pre-treatment, or treatment state, enabling adaptive optimization of region visibility without requiring manual intervention
2Manufacturing precision
If distinguishability is reduced during treatment state, then the precision of intervention is improved, but the loss of information increases
Solution Approach 1:
The patent applies local quality modification by selectively altering the display properties of the region of interest based on the treatment state. During treatment, specific visual characteristics (such as outline emphasis, color changes, or framing) are applied locally to the region of interest while maintaining other informational content, thereby enhancing precision of intervention without complete information loss
Solution Approach 2:
The patent introduces visual intermediaries such as frames, outlines, or symbolic indicators that mediate between the raw image data and the final display during treatment state. These intermediaries serve as additional layers of information that enhance precision by clearly delineating the region of interest while preserving the underlying anatomical information visible through or alongside these indicators
