Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple dynamic analyses are performed separately with different imaging conditions, then each analysis achieves optimal imaging quality, but the subject burden increases and radiation exposure accumulates
Solution Approach 1:
The patent combines multiple dynamic analyses into a single integrated imaging process. The imaging condition setting unit consolidates requirements from multiple analysis types (e.g., lung field region extraction, diaphragm displacement tracking, lung tissue behavior visualization) and generates a unified imaging condition set that satisfies all analyses simultaneously, thereby reducing the number of separate imaging sessions and cumulative radiation exposure.
Solution Approach 2:
The system designs the imaging condition setting unit to handle multiple analysis types universally. Instead of creating separate imaging protocols for each analysis, the unit evaluates all required analyses and determines a single set of imaging conditions (frame rate, dose, timing) that can serve multiple analysis purposes, making the imaging system multi-functional and reducing subject burden.
2Measurement precision
If imaging conditions are optimized for each dynamic analysis type, then analysis accuracy improves, but the complexity of imaging protocol management increases
Solution Approach 1:
The imaging condition setting unit performs preliminary evaluation of multiple dynamic analysis requirements before actual imaging. It proactively determines the optimal imaging conditions that satisfy all analyses in advance, creating a unified protocol that eliminates the need for complex post-hoc adjustments or multiple separate protocols, thereby reducing management complexity while maintaining accuracy.
Solution Approach 2:
The system dynamically adjusts imaging parameters (frame rate, radiation dose, timing) based on the combined requirements of multiple analyses. The imaging condition setting unit evaluates the parameter needs of different analyses and synthesizes an optimized parameter set that meets all requirements, transforming complex multi-parameter optimization into a streamlined automated process.
3Reliability
If separate imaging sessions are conducted for each dynamic analysis, then each analysis receives dedicated optimization, but the total imaging time and subject burden increase
Solution Approach 1:
The patent merges multiple separate imaging sessions into a single integrated session. The imaging condition setting unit coordinates multiple dynamic analyses to be performed concurrently or sequentially within one imaging acquisition, using unified imaging conditions that satisfy all analyses, thereby reducing total imaging time while maintaining the reliability needed for each specific analysis type.
