Anatomical Map Region Filling for High-Resolution Cardiac Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anatomical mapping techniques struggle with regional resolution issues, leading to artifacts and omission of essential sections in regions of interest due to hidden areas during selection, which affects the accuracy and quality of procedures like cardiac ablation.
Innovation Solution
A system and method that uses a processor to identify the perimeter and unselected areas within a selected region on an anatomical map, applying techniques like flood fill and geodesic path formation to ensure all areas are included at higher resolution, enhancing the accuracy of regional mapping.

1Productivity
If fast anatomical mapping is used to improve procedural efficiency, then mapping speed increases, but regional resolution deteriorates leading to artifacts and omission of essential sections
Solution Approach 1:
The anatomical map is divided into multiple regions with different resolution levels. A first region (region of interest) is displayed at high resolution while a second region is displayed at low resolution. This segmentation allows the system to maintain high mapping speed overall while providing detailed visualization where clinically necessary.
Solution Approach 2:
Different regions of the anatomical map are assigned different quality levels (resolution). The first region surrounding a selected point is rendered at high resolution to capture essential anatomical details, while the second region is rendered at low resolution to maintain overall context without consuming excessive processing resources.
2Manufacturing precision
If high resolution is applied to the entire anatomical map, then mapping accuracy improves, but processing time and computational resources increase significantly
Solution Approach 1:
Instead of uniformly applying high resolution across the entire anatomical map, the system applies high resolution locally only to the first region surrounding the selected point. This localized approach maintains mapping accuracy where needed while significantly reducing the computational burden and processing time.
Solution Approach 2:
The system applies high resolution processing only partially to the necessary region rather than excessively to the entire map. The first region receives high resolution treatment while the second region uses low resolution, providing sufficient detail for clinical decision-making without the prohibitive cost of full high-resolution rendering.

AI summary
A method includes, receiving, on a surface of an anatomical map of a patient organ having a first presentation, a selection of a first selected region, which is intended to have a second presentation, different from the first presentation. A perimeter of the first selected region, and at least an unselected area positioned within the first selected region, are identified. A second selected region is produced, the second selected region includes the first selected region and the unselected area. The anatomical map, having the second presentation applied to the second selected region, is displayed.
