Coronary Artery Visualization Integrating Perfusion and Flow Impediment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for assessing coronary artery health and myocardial perfusion, such as CT angiography, lack comprehensive visualization tools to integrate perfusion measures, geometry, and flow impediments, limiting their ability to provide a unified risk assessment for cardiovascular events.
Innovation Solution
A method and system that overlay perfusion measures of myocardial tissues and coronary arteries on a single image, incorporating geometry and flow impediment data from spectral CT scans, allowing for a unified visualization and predictive analytics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate visualization methods are used for perfusion measures, geometry, and flow impediment, then comprehensive assessment capability is improved, but inspection time and complexity increase
Solution Approach 1:
The patent combines multiple separate visualization methods (perfusion measures, geometry, and flow impediment) into a single integrated visualization that displays all three parameters simultaneously. This merging allows clinicians to perform comprehensive risk assessment while reducing inspection time, as all necessary information is presented in one unified view rather than requiring separate examinations of multiple images or data sets.
2Measurement precision
If separate visualizations are used for different coronary artery parameters, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system merges multiple parameter visualizations into a single integrated display while preserving the precision of individual measurements. The unified visualization presents perfusion measures, geometry, and flow impediment together, allowing accurate measurement of each parameter without requiring separate complex visualization systems.
Solution Approach 2:
The visualization system is designed to be multi-functional, capable of displaying multiple different parameters (perfusion, geometry, flow impediment) within a single unified interface. This universal approach maintains measurement precision for each parameter type while avoiding the need for multiple separate specialized systems.
3Reliability
If comprehensive data integration is implemented, then predictive analytics capability is improved, but data processing complexity increases
Solution Approach 1:
The patent integrates comprehensive data from multiple sources (perfusion measures, geometry, flow impediment) into a unified visualization framework. This merging enables improved predictive analytics by allowing simultaneous analysis of all parameters, while the integrated approach manages data processing complexity through a cohesive system architecture rather than requiring separate processing for each parameter.

AI summary
A method for visualization may include: obtaining data of a first perfusion measure of myocardial tissues of a patient; obtaining data of a geometry of a coronary artery of the patient; obtaining data of a second perfusion measure of the coronary artery; obtaining data of a flow impediment measure along the coronary artery based on the data of the second perfusion measure of the coronary artery; and visualizing, on a single image, the first perfusion measure of the myocardial tissues and the coronary artery, the coronary artery being overlaid with the first perfusion measure on the single image, the visualized coronary artery representing the geometry of the coronary artery and the flow impediment measure along the coronary artery.
