MR Image Series Selection via Signature Similarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for evaluating and displaying MR image series in a workflow-based approach are inefficient in selecting the most appropriate image series for specific segments, leading to suboptimal radiological evaluations.
Innovation Solution
A method is developed to determine the most similar image series from a set by compiling signatures based on attributes, comparing these signatures to prespecified sets, and selecting the image series with the greatest similarity for each segment, allowing for automated selection and adaptation to various conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual selection of image series for layout segments is performed, then flexibility in selection is maintained, but time consumption and efficiency are reduced
Solution Approach 1:
The system performs automatic selection of image series for layout segments using similarity comparison between signatures and signature sets, enabling the system to serve itself without manual intervention. This resolves the contradiction by automating the selection process while maintaining appropriate flexibility through configurable similarity thresholds and multiple candidate selection.
2Productivity
If automatic selection of image series is implemented, then time efficiency is improved, but selection accuracy may deteriorate
Solution Approach 1:
The system uses similarity comparison as a feedback mechanism to automatically select image series that best match the desired characteristics for each layout segment. By calculating similarity metrics between signatures and signature sets, the system can objectively determine the most appropriate image series, maintaining accuracy while improving efficiency.
Solution Approach 2:
The system transforms the selection criterion into a measurable similarity parameter between signatures and signature sets. This parameter-based approach allows automatic selection while maintaining accuracy by quantitatively comparing image series characteristics against desired segment requirements.
3Quantity of substance
If multiple image series are displayed in layout segments, then information completeness is improved, but information overload and difficulty in identifying relevant images increases
Solution Approach 1:
The system applies different selection criteria and similarity thresholds to different layout segments based on their specific requirements. Each segment receives image series that are locally optimized for its purpose, making it easier for users to identify relevant images in each segment without being overwhelmed by irrelevant information from other segments.
4Adaptability or versatility
If similarity-based automatic determination is used, then adaptability to various conditions is improved, but system complexity increases
Solution Approach 1:
The signature-based selection system serves multiple functions: it can select image series for different layout segments, support various similarity metrics, handle different image characteristics, and provide configurable selection criteria. This universal approach increases adaptability while managing complexity through a unified selection framework that can be configured for different scenarios.

AI summary
For the determination of an image series from a set of a number of image series, in each case of a signature is compiled for each of the number of image series. This signature is formed from a set of attributes of the respective image series. A signature from the signatures for the image series is ascertained that is most similar to a prespecified signature set. An action is performed with the image series whose signature was ascertained as the most similar signature.
