Ventricle Wall Motion Visualization Composite Image
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for analyzing cardiac ventricle motion in digital medical images lack effective visualization of the ventricle wall's transition between systolic and diastolic phases, making it difficult to accurately depict and understand the heart's motion over a cardiac cycle.
Innovation Solution
A system that processes medical images to identify End Diastolic (ED) and End Systolic (ES) frames, and creates a composite image with graphic visualization by assigning changing colors to ventricle wall outlines, allowing for the visualization of ventricle wall motion from systolic to diastolic phases, using a processing device with an image data processor, vision unit, and frame grabber unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple separate images or videos are used to show ventricle wall motion, then the motion can be captured over time, but it becomes difficult to visualize and understand the complete cardiac cycle in a single view
Solution Approach 1:
The patent combines multiple ventricle wall outline images from different cardiac phases into a single composite image. Each outline is extracted from separate frames and merged together with distinct visual characteristics (different grayscale levels or colors) to represent different phases of the cardiac cycle, allowing complete visualization in one image
Solution Approach 2:
The patent adds a visual dimension (grayscale intensity or color) to differentiate temporal phases. By mapping temporal information (cardiac phases) to a visual attribute dimension (brightness/color), the system enables simultaneous display of multiple time points in a single spatial image without confusion
2Measurement precision
If ventricle wall motion is analyzed frame by frame, then detailed motion can be observed, but it requires significant time and effort to interpret the complete cardiac cycle
Solution Approach 1:
The system performs preliminary processing by automatically extracting ventricle wall outlines from multiple frames and preparing them for composite display. This preprocessing organizes the data so that the complete cardiac cycle is ready for immediate visualization without requiring manual frame-by-frame analysis, reducing interpretation time while preserving motion details
3Ease of manufacture
If traditional grayscale imaging is used, then the images are simple to acquire, but they lack the visual distinction needed to clearly show ventricle wall motion phases
Solution Approach 1:
The patent applies different visual qualities (grayscale levels or colors) to different parts of the image corresponding to different cardiac phases. Each ventricle wall outline is assigned a distinct visual characteristic based on its temporal phase, enabling clear differentiation of motion stages while maintaining the simplicity of the overall imaging approach
Data Source
AI summary
A method for graphic visualization of ventricle wall motion includes acquiring medical imaging data frames depicting at least one cardiac cycle, identifying a ventricle wall outline in at least a portion of the plurality of image frames, determining end systolic and end diastolic frames belonging to a same cardiac cycle, copying the ventricle wall outline image from the ES and the ED frames, creating a composite image frame that includes the copied ventricle wall outline images, assigning a first color to the ES and a second color to the ED outline images of the composite frame, and providing the composite frame for displaying, printing, and/or storing in memory. A system for implementing the method and a non-transitory computer-readable medium are also disclosed.
