Medical Image Display Apparatus Annotation Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical image display systems do not effectively allow doctors to understand how computer-aided diagnosis (CAD) analysis results influence their interpretation of medical images, leading to potential oversight of diseased regions.
Innovation Solution
A medical image display apparatus that allows for the display of primary and secondary interpretation results in a distinguishable manner, along with the CAD analysis results, using different annotations such as marks or text, and prohibits editing of the primary interpretation after displaying the CAD analysis results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the primary interpretation result is completely deleted after referring to CAD analysis results, then the display is simplified, but it becomes difficult to understand how the CAD analysis affected the final interpretation
Solution Approach 1:
The annotation is segmented into multiple components: the base annotation representing the primary interpretation, and overlay elements representing CAD analysis results and secondary interpretations. This segmentation allows each component to be displayed and managed independently while maintaining their relationships, resolving the contradiction between display simplicity and information completeness.
Solution Approach 2:
The patent implements a nested display structure where the secondary interpretation annotation is superimposed on the primary interpretation annotation. The CAD analysis results are displayed as overlay elements within the same annotation region. This nesting allows multiple layers of information to coexist in a compact form, maintaining both simplicity and information integrity.
2Stability of the object's composition
If the interpretation result is displayed in the same mode before and after referencing CAD analysis, then consistency is maintained, but the impact of CAD analysis on the final interpretation cannot be understood
Solution Approach 1:
The patent uses color coding to differentiate between primary interpretation annotations and secondary interpretation annotations. The overlay elements representing CAD results and secondary interpretations are displayed with distinct colors or visual styles, allowing doctors to easily identify changes while maintaining the overall annotation structure. This visual differentiation resolves the contradiction between consistency and information visibility.
3Loss of information
If multiple annotations (primary interpretation, CAD results, secondary interpretation) are displayed together, then the impact of CAD analysis can be understood, but the display becomes complex and difficult to interpret
Solution Approach 1:
The patent merges multiple annotation elements into a unified annotation structure. The primary interpretation annotation serves as the base, with CAD analysis results and secondary interpretations integrated as overlay elements within the same display region. This merging reduces visual clutter while preserving all necessary information, resolving the contradiction between information completeness and display simplicity.
Data Source
AI summary
The processor displays a medical image, receives an input of a primary interpretation result by a user interpreting the medical image, displays an annotation representing the primary interpretation result, acquires an analysis result for the medical image, displays an annotation representing the analysis result, receives an input of a secondary interpretation result by the user interpreting the medical image after displaying the analysis result, and displays the annotation representing the primary interpretation result and an annotation representing the secondary interpretation result in a distinguishable manner.
