3D-to-2D Ablation Lesion Mapping for Pulmonary Vein Ring Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Assessing the continuity and effectiveness of lesions formed during ablation procedures, particularly in pulmonary veins, is difficult due to the challenges in verifying the formation of a continuous ring along the inner circumference in three-dimensional anatomical maps.
Innovation Solution
A system and method that transforms a three-dimensional section of a patient organ into a two-dimensional map, allowing for the visualization and checking of lesion continuity by overlapping symbols, and providing recommendations for additional ablation points to ensure complete lesion coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ablation procedures are performed in three-dimensional anatomical maps, then the accuracy of lesion placement is improved, but the difficulty of verifying lesion continuity worsens
Solution Approach 1:
The patent creates a two-dimensional copied representation of the three-dimensional anatomical map and lesion data. This 2D copy allows clinicians to easily verify lesion continuity without sacrificing the spatial accuracy of the original 3D procedure. The copying principle resolves the contradiction by providing a simplified view that maintains measurement precision while eliminating verification difficulty.
Solution Approach 2:
The patent transforms three-dimensional lesion data into a two-dimensional representation, effectively changing the dimensionality of the data presentation. This dimensionality change allows the complex 3D spatial relationships to be visualized in a simpler 2D format, making continuity verification straightforward while preserving the accuracy information from the original 3D procedure.
2Reliability
If multiple ablation points are distributed along the circumference, then the coverage of the ablated region is improved, but the time required to verify lesion continuity worsens
Solution Approach 1:
The patent creates a 2D copied representation that displays all multiple ablation points and their corresponding lesions in a single visual field. This copying approach allows clinicians to verify the continuity and coverage of multiple lesions simultaneously, dramatically reducing verification time while maintaining reliable coverage assessment.
Solution Approach 2:
The patent merges multiple lesion data points from different ablation locations into a single integrated 2D map view. By combining all lesion information into one unified representation, the system allows rapid assessment of overall coverage and continuity without requiring separate verification steps for each individual lesion.
3Reliability
If a continuous ring of lesions is formed along the inner circumference, then the effectiveness of EP wave blockage is improved, but the complexity of assessing lesion continuity worsens
Solution Approach 1:
The patent transforms the complex three-dimensional assessment of lesion continuity into a simplified two-dimensional representation. In this 2D view, the continuous ring structure becomes visually apparent and easy to assess, reducing the complexity of evaluation while maintaining the reliability of EP wave blockage effectiveness determination.
Solution Approach 2:
The patent creates a 2D copied map that simplifies the visual assessment of whether a continuous ring of lesions has been formed. This copied representation makes it straightforward to evaluate the completeness and continuity of the lesion ring, reducing assessment complexity while preserving the reliability of the blockage effectiveness evaluation.

AI summary
A method includes, receiving: (i) a selected three-dimensional (3D) section that has been ablated in a patient organ in accordance with a specified contour, and (ii) a dataset, which is indicative of a set of lesions formed during ablation of the selected 3D section. The selected 3D section is transformed into a two-dimensional (2D) map, and checking, on the 2D map, whether the set of lesions covers the specified contour.
