Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for annotating medical images lack an efficient method to automatically group annotations related to the same anatomical object across multiple images, making it difficult to structure and process this information effectively.
Innovation Solution
A system that displays medical images and receives user input to create annotations, using geometric information and predefined rules to automatically group annotations based on properties such as position, orientation, and overlap, allowing for the identification of annotations belonging to the same anatomical object, even across different images or image datasets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If annotations are stored separately for each image without automatic grouping, then storage and management are simple, but it becomes difficult to structure and process annotations related to the same anatomical object across multiple images
Solution Approach 1:
The system performs preliminary grouping of annotations based on geometric relationships and predefined rules before information extraction or processing. By automatically detecting groups of annotations related to the same anatomical object in advance, the system structures the data proactively, enabling more efficient subsequent processing without adding complexity to individual annotation operations.
Solution Approach 2:
The system uses self-service mechanisms by automatically analyzing geometric information of annotations and applying predefined rules to group them without requiring manual intervention. The geometric relationships and rules define the grouping criteria autonomously, allowing the system to structure annotations independently while maintaining simplicity in the overall architecture.
2Loss of information
If manual grouping of annotations is implemented, then annotations can be accurately organized by anatomical object, but it requires significant user time and effort
Solution Approach 1:
The system replaces the mechanical manual process of annotation grouping with an automated computational process. By substituting user actions with automatic geometric analysis and rule-based detection, the system maintains accurate information structuring while eliminating the time-consuming manual effort previously required for organizing annotations by anatomical object.
Solution Approach 2:
The system changes the parameters of annotation organization from manual categorical grouping to automated geometric parameter-based grouping. By utilizing geometric information such as position, orientation, and spatial relationships as grouping parameters, the system automatically structures annotations according to their anatomical object associations without requiring user intervention, thus preserving information structure while minimizing time loss.
3Productivity
If annotations are processed without automatic grouping, then processing is straightforward, but machine accessibility and automated information extraction are limited
Solution Approach 1:
The system performs preliminary automatic grouping of annotations based on geometric relationships before information extraction processes. By pre-organizing annotations into groups corresponding to anatomical objects using predefined rules, the system enhances machine accessibility and facilitates automated information extraction in advance, improving productivity without significantly increasing overall processing complexity.
Solution Approach 2:
The system introduces an intermediary automatic grouping mechanism that bridges raw annotations and final information extraction. This intermediary process uses geometric information and predefined rules to create structured groups, serving as a mediator that enhances machine accessibility and facilitates downstream automated processing while maintaining manageable complexity through rule-based operations.
