Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In endoscopic lesion detection, users struggle to determine how long ago a detected lesion was captured, making it difficult to adjust the endoscope position for re-capture.
Innovation Solution
An information processing device that sequentially acquires images, performs lesion detection, and displays the time lapse since capture on a display, allowing users to easily grasp the time elapsed since lesion detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real-time lesion detection processing is performed on endoscopic images, then lesion detection capability is improved, but the user cannot grasp the time elapsed since lesion capture making position adjustment difficult
Solution Approach 1:
The patent introduces a time lapse display as an intermediary element between the lesion detection system and the user. This visual indicator mediates the information gap by translating the temporal distance between current and past images into an intuitive display, enabling users to quickly comprehend how long ago the lesion was captured without adding complex interface elements.
Solution Approach 2:
The system provides feedback to the user about the temporal relationship between the current image and the detected lesion image. By displaying the time lapse, the system gives the user immediate information about when the lesion was captured relative to now, allowing for rapid position adjustment without requiring the user to manually track or calculate time differences.
2Measurement precision
If the endoscope position is adjusted to re-capture the lesion, then detection accuracy is improved, but the user cannot easily determine how much to move the endoscope
Solution Approach 1:
The time lapse display serves as an intermediary that preserves and communicates temporal information that would otherwise be lost during the examination process. It translates the abstract concept of time elapsed into a visual indicator that directly informs the user about the temporal distance, preventing information loss and enabling precise position adjustment.
Solution Approach 2:
The system changes the parameter presentation from raw temporal data (frame numbers, timestamps) to a simplified time lapse metric that is directly meaningful to the user. This parameter transformation makes the time information accessible and actionable, allowing users to quickly determine how much to adjust the endoscope position without dealing with complex time data.
3Productivity
If detection processing is performed on sequentially acquired images, then lesion detection coverage is improved, but the user cannot grasp the timing of detected lesions during examination
Solution Approach 1:
The time lapse display acts as an intermediary that bridges the gap between comprehensive lesion detection coverage and temporal awareness. It processes the temporal information from sequentially acquired images and presents it in a way that maintains detection coverage while making timing information accessible to the user during the examination.
Solution Approach 2:
The system provides continuous feedback about the timing of detected lesions relative to the current examination moment. This feedback mechanism ensures that users remain aware of when lesions were captured, maintaining temporal information awareness throughout the examination while preserving comprehensive detection coverage through continuous image processing.
