Intracardiac 3D EP Mapping for Single-View Ablation Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current EP cardiac maps are cumbersome to view ablation targets or sites, requiring rotation and zooming from multiple views, and are viewed from outside the heart chamber, making it difficult to visualize cardiac structures clearly.
Innovation Solution
A system and method for generating a 3D electrophysiological map from within the cardiac structure using imaging devices positioned at optimal locations determined by algorithms like the 3D art gallery and skeleton axis, providing a complete visualization of cardiac structures without the need for rotation or zooming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If EP cardiac maps are viewed from outside the heart chamber, then the mapping data can be displayed on a monitor, but the visualization of ablation sites within cardiac structures is cumbersome and requires rotation and zooming
Solution Approach 1:
The patent inverts the conventional viewing perspective by positioning the imaging device inside the heart chamber rather than outside. This allows the physician to view ablation sites directly from within the cardiac structure, eliminating the need for rotation and zooming operations. The imaging device captures images from the interior perspective, providing immediate visualization of pulmonary veins and ablation targets without requiring manipulation of the EP map view.
2Loss of information
If multiple views are used to visualize ablation sites, then complete coverage of cardiac structures is achieved, but the complexity of viewing and interpreting the data increases
Solution Approach 1:
The patent merges multiple viewing perspectives into a single integrated view by positioning the imaging device to capture the entire cardiac structure from an optimal interior location. The processor combines the EP mapping data with the interior images to create a unified visualization that displays ablation sites, pulmonary veins, and cardiac structures in one comprehensive view, eliminating the need to switch between multiple perspectives or perform rotation and zooming operations.
3Measurement precision
If imaging devices are positioned within the cardiac structure, then complete visualization of internal cardiac structures is achieved, but the complexity of positioning and obtaining optimal images increases
Solution Approach 1:
The patent performs preliminary positioning of the imaging device within the cardiac structure before the ablation procedure begins. The processor determines the optimal location for the imaging device to maximize visualization of all relevant cardiac structures and ablation targets. This preliminary setup ensures that once positioned, the imaging device provides comprehensive views without requiring further adjustment during the procedure, reducing operational complexity while maintaining high measurement precision.
