Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a three-dimensional tracking process is performed to obtain wall movement information, then the quantity of obtained information is improved, but the precision of the evaluation is worsened because the three-dimensional information is converted into two-dimensional parameters
Solution Approach 1:
The patent applies dimensionality change by calculating local volumes (three-dimensional metric) between endocardium and epicardium instead of converting three-dimensional tracking data into two-dimensional parameters. This preserves the spatial information in three dimensions, enabling accurate calculation of wall movement, thickening, and other cardiac functions while maintaining the full three-dimensional character of the ultrasound data.
2Measurement precision
If three-dimensional position information is used to calculate local volume and area, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The patent segments the cardiac wall into discrete three-dimensional position points (endocardium and epicardium surfaces) that can be individually tracked and measured. By dividing the complex cardiac structure into manageable point-based representations, the system can calculate local volumes and areas through systematic mathematical operations on these segmented points, making the complex three-dimensional calculations more tractable.

AI summary
Position coordinate information of each point three-dimensionally forming a tissue corresponding to a diagnosis target at each time phase is obtained, a quantitative value for evaluating the movement of the tissue corresponding to the diagnosis target is calculated by using the position information, and the result is output in a predetermined form. Accordingly, since the quantitative value for evaluating the movement is calculated by using the three-dimensional position coordinate information without converting wall movement information obtained by a three-dimensional tracking process into two-dimensional information, it is possible to provide medical information with a higher degree of precision.
