Medical Image Display Apparatus Calcification Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical image display systems struggle to accurately represent calcification distribution in three-dimensional heart valves from two-dimensional cross-sectional planes, leading to inaccurate estimates during surgery planning, affecting both heart valve and other anatomical structure surgeries.
Innovation Solution
A medical image display apparatus that obtains volume data, specifies an observation cross-sectional plane, identifies regions of interest, and displays this information to provide a more comprehensive understanding of calcification distribution, allowing for more accurate surgical planning by visualizing calcification positions and amounts beyond the cross-sectional plane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If only two-dimensional cross-sectional plane images are used for observation, then the simplicity of image display is maintained, but the accuracy of recognizing calcification distribution and estimating surgical parameters deteriorates
Solution Approach 1:
The patent applies dimensionality change by projecting three-dimensional calcification distribution data onto the two-dimensional cross-sectional plane. This allows the display to maintain its simple 2D format while incorporating additional dimensional information through overlaid visual cues such as color-coded regions, transparency variations, or symbolic representations that encode depth and volume data, thereby resolving the contradiction between display simplicity and measurement accuracy.
2Measurement precision
If three-dimensional calcification distribution is fully visualized, then the accuracy of surgical planning is improved, but the complexity of the display system increases
Solution Approach 1:
The patent segments the three-dimensional calcification distribution into discrete volumetric elements or regions that can be individually characterized and represented. By dividing the complex 3D data into manageable segments, the system can overlay this information on the 2D cross-sectional display without requiring a fully complex 3D visualization system, thus improving surgical planning accuracy while controlling display system complexity.
Solution Approach 2:
The patent creates a simplified representation or copy of the three-dimensional calcification distribution that can be overlaid on the two-dimensional display. This copy contains the essential spatial and volumetric information needed for accurate surgical planning but is rendered in a format compatible with the existing 2D interface, avoiding the need for a completely complex 3D visualization system.
