3D Cardiac Visualization Correlating Tissue Defects with Coronary Arteries
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multiphase computerized tomography analysis techniques face difficulties in correlating measured cardiac tissue defects with corresponding coronary artery issues due to the two-dimensional representation of heart muscle, making it challenging to identify and visualize anatomical relationships.
Innovation Solution
A system and method that generate a three-dimensional model of the cardiac region of interest, measure functional parameters, create a spatial relation map, and combine these with a three-dimensional vessel structure model using a common coordinate system to produce an output image that visually correlates cardiac tissue defects with coronary artery positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a two-dimensional illustration of the heart muscle is used to display measurements, then the presentation is simple and conventional, but the ability to correlate measurements with anatomical information (such as coronary artery positions) is poor
Solution Approach 1:
The patent transitions from two-dimensional display to three-dimensional visualization by generating a 3D model of the heart muscle from multiphase CT images. This dimensional upgrade allows functional parameter maps to be spatially correlated with anatomical structures such as coronary arteries in three-dimensional space, resolving the information loss problem while maintaining manageable system complexity through software-based processing
2Difficulty of detecting and measuring
If conventional two-dimensional analysis techniques are used, then the analysis process is straightforward, but the identification and correlation of defects in cardiac tissue with problems in coronary arteries is very difficult
Solution Approach 1:
The patent merges functional parameter data (such as myocardial perfusion or wall motion) with anatomical 3D models of the heart and coronary arteries into a single integrated visualization. This combination allows clinicians to simultaneously view defect locations in cardiac tissue and their spatial relationship with coronary artery abnormalities, significantly reducing diagnostic difficulty and improving efficiency

AI summary
A system and method to generate an illustration of a cardiac region of interest of an imaged subject is provided. The method includes generating a three-dimensional model from a series of acquired images of the cardiac region of interest; measuring a series of values of at least one functional parameter of the cardiac region of interest; generating a map of a spatial relation of the plurality of values of the functional parameter in spatial relation to the three-dimensional model of the cardiac region of interest; generating a three-dimensional model of a vessel structure leading to the cardiac region of interest; generating an output image that includes combining the three-dimensional model of the cardiac region of interest, the map of the series of values of the functional parameter, and the three-dimensional model of the vessel structure in spatial relation to one another relative to a common coordinate system.
