Dynamic Image Analysis Device Suitability Judgment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dynamic image analysis devices rely on subjective judgments to determine the suitability of analysis results for diagnosis, lacking an objective method to assess the reliability and usability of dynamic images obtained through radiography.
Innovation Solution
A dynamic image analysis system that includes a hardware processor to acquire dynamic images from radiography, perform suitability judgments based on the images or analysis results, and output unsuitability information when the images are not suitable for analysis, preventing the display of unsuitable analysis images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If subjective judgment by technologist is used to determine suitability of dynamic image analysis results, then the system can operate with simple processing, but the reliability and objectivity of the diagnosis is compromised
Solution Approach 1:
The dynamic image analysis device automatically performs suitability judgment using objective criteria (feature amounts extracted from the dynamic image and analysis results) without requiring technologist intervention. The system evaluates whether the dynamic image is suitable for analysis based on predefined conditions and automatically determines suitability, making the device self-sufficient in assessing its own output quality.
Solution Approach 2:
The invention introduces specific measurable parameters (feature amounts) to objectively assess the suitability of dynamic images. By extracting and evaluating quantitative features from the images and analysis results, the system transforms subjective judgment into objective parameter-based assessment, improving reliability while maintaining manageable complexity through automated processing.
2Productivity
If dynamic images with insufficient quality are analyzed, then productivity is maintained, but the reliability of analysis results deteriorates
Solution Approach 1:
The suitability judgment is performed before the dynamic image analysis is executed. By evaluating feature amounts and determining suitability in advance, the system prevents wasting computational resources on unsuitable images, thereby maintaining productivity while ensuring that only reliable images undergo analysis.
Solution Approach 2:
The system provides feedback regarding the suitability of dynamic images for analysis. By evaluating feature amounts and communicating suitability status, the system enables operators to understand why certain images are unsuitable and make informed decisions about whether to proceed with analysis or acquire new images.
