3D Cardiac Visualization Integrating Angiography and Physiology
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for planning percutaneous coronary interventions (PCI) are limited by the separation of external cardiac test data, intravascular imaging data, and physiologic data, which hinders effective visualization and simulation of stent deployment effects on blood flow to the myocardium.
Innovation Solution
A system that generates a three-dimensional graphical representation of the heart integrating angiography, IVUS images, pressure measurements, and nuclear stress test data, allowing clinicians to simulate stent deployment and evaluate its physiologic effects on blood flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If separate tests are used for external cardiac test data, intravascular imaging data, and physiologic data, then each test can be performed independently, but the efficacy is limited by the inability to integrate and visualize the data together for comprehensive treatment planning
Solution Approach 1:
The patent combines multiple separate diagnostic data sources (external cardiac test data, intravascular imaging data, and physiologic data) into a single integrated three-dimensional graphical representation. This merging allows clinicians to view all relevant information simultaneously in one unified visualization, resolving the technical contradiction by prioritizing complete information availability over system simplicity.
2Ease of operation
If clinicians rely on conventional angiography and physiologic measurements separately, then the diagnostic process is simpler, but the ability to plan therapeutic intervention is limited by the lack of meaningful connection between the data
Solution Approach 1:
The patent transforms traditional two-dimensional angiographic images and separate physiologic measurements into a three-dimensional graphical representation that spatially integrates all data types. This dimensional enhancement allows clinicians to easily analyze the relationships between anatomical structures and physiologic parameters simultaneously, resolving the contradiction by making complex integrated data visually accessible without increasing operational complexity.
3Manufacturing precision
If detailed integrated data visualization is provided, then treatment planning accuracy is improved, but the complexity of the visualization system increases
Solution Approach 1:
The patent segments the integrated visualization system into distinct functional components: external cardiac test data integration, intravascular imaging data integration, physiologic data integration, and simulated stent deployment capabilities. Each component handles specific data types or functions independently, allowing the system to provide comprehensive detailed visualization while managing complexity through modular organization of the visualization elements.
