3D Organ Simulation Display Tracing Physical Values
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional technologies struggle to effectively trace the characteristic movements of internal organs like the heart, lungs, and kidneys, as they are not specialized for the complex movements of these organs, making it difficult to visualize their behavior over time.
Innovation Solution
A computer-readable medium stores a display program that detects and extracts physical values from tetra elements in a 3-dimensional simulation model of an internal organ at different times, allowing for the display of these values to trace the behavior of the organ over time by specifying a line within the model and graphing the physical values at each time step.

Engineering Contradiction Analysis
1Measurement precision
If conventional computer graphics technology is used to display simulation results, then distribution by color can be indicated, but it is difficult to trace characteristic movements of internal organs like the heart
Solution Approach 1:
The patent segments the 3D simulation model into multiple cross-sectional planes (e.g., short-axis, long-axis views) and extracts specific calculation elements from each plane. This segmentation allows the system to focus on and trace movements in specific regions of interest within the organ, making it possible to track characteristic movements that would be lost in a full-color distribution display.
Solution Approach 2:
The patent extracts specific calculation elements and their physical values from the overall simulation model at multiple time points. By taking out and comparing corresponding elements across different time points, the system can trace the movement and behavior of specific organ regions, overcoming the limitation of conventional display methods that show static color distributions without temporal tracking capability.
2Loss of information
If calculation elements are checked to extract partial values, then specific physical values can be obtained, but the process becomes complex and difficult to visualize
Solution Approach 1:
The patent creates a universal comparison framework that works across different cross-sectional planes and time points. By establishing corresponding relationships between calculation elements in different planes and times, the system can simultaneously track multiple physical values (displacement, strain, stress) without requiring separate complex processes for each, thus reducing overall system complexity while maintaining information completeness.
Solution Approach 2:
The patent adds the time dimension to the spatial comparison of calculation elements. By comparing elements across multiple time points (t1, t2, t3, etc.), the system transforms static spatial data into dynamic temporal-spatial data, enabling movement tracking without increasing the complexity of element checking procedures.
3Illumination intensity
If conventional visualization technology is used, then color distribution can be shown, but characteristic movements of the heart and other internal organs cannot be traced
Solution Approach 1:
The patent performs preliminary identification and correspondence establishment of calculation elements across different time points before actual movement analysis. By pre-establishing which elements correspond to each other in different cross-sectional planes and time points, the system ensures accurate movement tracing while maintaining clear visual presentation of physical values.
Solution Approach 2:
The patent uses color coding to represent different physical values and their changes over time in specific calculation elements. By applying color changes to indicate displacement, strain, or stress variations in traced elements, the system maintains the visual clarity advantage of color distribution displays while adding the capability to accurately trace and highlight specific organ movements.
