EP Map Dimming GUI for ROI-Focused Cardiac Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrophysiological (EP) maps in cardiac procedures are difficult to interpret due to visual overload outside regions of interest (ROIs), which hinders accurate identification of arrhythmogenic areas and decision-making during ablation.
Innovation Solution
A system and method that allows users to adjust the level of dimming and deemphasize the EP map outside ROIs using a graphical user interface (GUI), highlighting the ROIs for focused analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the EP map displays all regions with full visibility, then complete anatomical information is provided, but visual overload occurs outside regions of interest making interpretation difficult
Solution Approach 1:
The patent applies local quality by differentiating the visual presentation of different map regions. Regions of interest (ROIs) are highlighted with enhanced visual characteristics (brighter, more prominent) while non-ROI areas are dimmed or de-emphasized. This allows the map to provide complete anatomical information throughout while simultaneously improving interpretability by directing attention to clinically relevant areas through localized visual enhancement.
2Ease of operation
If the EP map highlights regions of interest with enhanced visibility, then focused analysis is enabled, but contextual anatomical context is reduced
Solution Approach 1:
The patent implements dynamic visual adjustment where the degree of dimming or highlighting can be modified based on user interaction and procedural needs. The visual emphasis on ROIs is not fixed but can be adjusted to maintain appropriate anatomical context while enabling focused analysis when needed. This dynamic adjustment allows the system to adapt between providing comprehensive context and enabling focused examination of specific areas.

AI summary
A system included an input device and a processor. The processor is configured to (i) receive or generate an electrophysiological (EP) map comprising one or more regions of interest (ROIs), (ii) receive from a user, via the input device, a level of deemphasis the EP map required outside the ROIs, (iii) deemphasize the EP map outside the ROIs responsively to the required level, and (iv) display the deemphasized EP map to the user.
