Electro-Anatomical Map Quality Profile Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mapping systems for organs like the heart lack feedback on the quality of acquired points and do not provide insights into why a point is considered lower quality, making it difficult for users to understand the dominant parameters affecting the quality index.
Innovation Solution
A system and method that allow users to define a quality profile by grouping parameters such as annotation, location, and morphology, enabling the selection of weights for computing the quality index, and displaying a simplex with vertices representing each value, allowing for the acquisition of points within defined ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a quality index is computed using multiple parameters, then the quality assessment becomes more comprehensive, but the user cannot identify which specific parameters dominate the quality score
Solution Approach 1:
The patent segments the quality index into multiple discrete parameters (e.g., morphology, location, annotation, sharpness, stability). Each parameter is displayed separately with its individual score and weight, allowing users to see exactly which parameters contribute most to the overall quality assessment. This segmentation transforms the black-box quality index into transparent, analyzable components.
2Loss of information
If the system provides detailed feedback on all quality parameters, then users can understand point quality better, but the interface complexity increases
Solution Approach 1:
The patent extracts and highlights only the dominant parameters (those with the greatest impact on quality) for detailed display, while still providing access to all parameters. The interface shows a simplified view with top contributing parameters first, allowing users to quickly grasp the main quality issues without being overwhelmed by every single parameter detail.
Solution Approach 2:
The patent applies different levels of detail to different parameters based on their importance. Dominant parameters receive prominent display with detailed breakdowns, while less important parameters are shown in summary form. This local quality approach ensures critical information is emphasized without uniformly increasing interface complexity across all elements.
3Adaptability or versatility
If users can customize quality thresholds and weights, then the system becomes more adaptable to different mapping needs, but the system complexity increases
Solution Approach 1:
The patent provides pre-configured quality profiles with default parameter weights and thresholds that are optimized for common mapping scenarios. Users can select from these pre-configured profiles without having to manually configure every parameter, thus gaining adaptability while minimizing the complexity burden. The system performs the complex configuration work in advance.
Solution Approach 2:
The patent implements dynamic quality profiles where users can adjust weights and thresholds interactively, and the system automatically recalculates and updates the quality assessments in real-time. This dynamic approach allows customization without requiring complex manual reconfiguration, as the system adapts automatically to user preferences and mapping conditions.
Data Source
AI summary
A system, method and user interface that allows a user to define a quality profile for acquiring points. The system, method and user interface divide the parameters across the quality index into groups. Such groups may include annotation, location and morphology, for example. The groups allow a user to select the weight of each group for computing the quality index. Each parameter may be assigned a score, such as from 1-5, for example, where a lower score defines a lower quality and a higher score defines a higher quality. Through a proper acquisition method, the user may be able to acquire points with a customized quality profile.
