Electrophysiological Map Quality Visualization via Color Modulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electrophysiological mapping systems fail to provide clear, real-time feedback on the quality and density of cardiac electrophysiological data, making it difficult for physicians to identify areas requiring additional data acquisition for optimal spatial coverage and quality.
Innovation Solution
A system that scores each data point based on quality metrics, divides the cardiac chamber map into regions, and modulates color luminance or saturation to indicate lower quality areas, providing clear visual feedback on data quality and guiding additional data collection.

Engineering Contradiction Analysis
1Loss of information
If electrophysiological data is visualized on a map without quality indicators, then the map provides comprehensive spatial coverage, but the physician cannot identify areas with insufficient data quality
Solution Approach 1:
The patent applies color changes by modulating the luminance or saturation of colors on the electrophysiological map to represent different data quality levels. High-quality data points are displayed with normal color intensity, while low-quality data points are displayed with reduced luminance or saturation, creating a visual distinction that helps physicians quickly identify areas requiring additional data acquisition without adding complex separate indicators.
2Measurement precision
If the system provides detailed quality feedback for each data point, then data quality assessment is comprehensive, but the visualization becomes cluttered and difficult to interpret
Solution Approach 1:
The patent applies local quality by differentiating the visualization treatment based on the quality of individual data points or regions. Instead of uniform visualization, the system dynamically adjusts the luminance or saturation of colors locally according to data quality metrics, allowing high-quality areas to be displayed with full detail while low-quality areas are subtly dimmed or desaturated, providing comprehensive quality assessment without overwhelming the physician with uniform detailed information everywhere.
Solution Approach 2:
The patent adds a visual dimension to data quality representation by using luminance or saturation as an additional visual attribute beyond the standard electrophysiological color coding. This dimensional addition allows quality information to be encoded in the existing color visualization without requiring separate graphs, tables, or additional display elements, maintaining ease of interpretation while providing comprehensive quality feedback.
3Quantity of substance
If additional data points are acquired to improve spatial coverage, then mapping completeness increases, but the procedure time increases
Solution Approach 1:
The patent implements feedback by providing real-time visual information about data quality through luminance or saturation modulation on the map. This immediate feedback allows physicians to identify low-quality regions and make informed decisions about where additional data acquisition is necessary, avoiding unnecessary data collection in already high-quality areas and focusing efforts only where improvement is needed, thereby optimizing the balance between data completeness and procedure time.

AI summary
Methods and systems indicate where in the EP map the quality of the EP values is below a required level. Indications provide real-time visual aid to the physician, helping him or her to assess in which areas of the cardiac chamber additional EP signals need to be acquired in order to achieve the desired quality and sufficient spatial coverage.
