Endoscope System Index Value Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Endoscopic diagnoses face challenges in acquiring index values necessary for disease diagnosis under current imaging conditions, as certain index values are not acquirable due to limitations in light source balance and observation settings.
Innovation Solution
An endoscope system with an imaging condition acquisition unit, index-value and imaging-condition storage unit, and guidance display unit that extracts and displays guidance for acquiring index values by switching to alternative imaging conditions, allowing for the acquisition of non-acquirable index values through the selection and calculation of index values based on stored correspondences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If imaging conditions are fixed for current endoscopic diagnosis, then diagnostic workflow is simple, but index values necessary for accurate disease diagnosis cannot be acquired
Solution Approach 1:
The system pre-stores multiple imaging conditions and their corresponding acquirable index values in a storage unit before actual diagnosis. When a diagnosis is performed, the system automatically retrieves and applies the appropriate pre-prepared imaging conditions, eliminating the need for manual configuration and ensuring that necessary index values can be acquired without complex real-time adjustments.
Solution Approach 2:
The system provides feedback to the user by displaying information about which index values can be acquired under current imaging conditions and suggesting alternative imaging conditions if required index values are not available. This feedback mechanism guides users to adjust imaging conditions appropriately to obtain necessary diagnostic data.
2Adaptability or versatility
If multiple imaging conditions are stored and managed, then all required index values can be acquired, but system complexity increases
Solution Approach 1:
The storage unit is designed to universally store multiple types of imaging conditions (e.g., different light source wavelengths, observation magnifications, focus settings) that can be applied across various diagnostic scenarios. This multi-functional storage system allows the endoscope to adapt to different diagnostic needs without requiring separate specialized systems for each imaging condition type.
Solution Approach 2:
The imaging condition extraction unit acts as an intermediary between the storage unit and the imaging system. It automatically retrieves the appropriate imaging conditions from storage based on diagnostic requirements and translates them into actionable parameters for the endoscope, simplifying the interface between data storage and practical application.
3Measurement precision
If imaging conditions are changed to acquire non-acquirable index values, then diagnostic accuracy improves, but observation time increases
Solution Approach 1:
By pre-storing multiple imaging conditions and their associated index value capabilities, the system enables rapid switching between conditions without requiring time-consuming manual adjustments. When a required index value is not available under current conditions, the system can quickly retrieve and apply the appropriate pre-configured imaging condition, minimizing observation time while ensuring diagnostic accuracy.
Solution Approach 2:
The system provides real-time feedback to users about which index values can be acquired under current imaging conditions. This feedback allows users to make informed decisions about whether to switch imaging conditions, balancing the need for accurate index value acquisition with time constraints in the diagnostic process.

AI summary
An endoscope system includes a storage medium that stores a plurality of correspondence between an imaging condition and a plurality of index values relating to a plurality of structures of an observation object, wherein the plurality of index values including a first index value acquirable under the first imaging condition and a second index value non-acquirable under the first imaging condition but acquirable under a second imaging condition, a monitor and a processor, coupled to the storage medium and the monitor. The processor is configured to: acquire an image of the observation object by using an endoscope; acquire a first imaging condition which represents an imaging condition of the image; refer to the plurality of index values and the imaging condition in the storage medium and extract the second imaging condition; and display guidance indicating that the second index value is acquirable under the extracted second imaging condition.
