Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 3D/4D contrast-enhanced imaging is performed with high imaging velocity to capture complete perfusion process, then diagnostic reliability is improved, but data processing load increases beyond current system computing power
Solution Approach 1:
The patent segments the imaging process into multiple phases (pre-contrast, arterial phase, venous phase, delayed phase) and acquires data selectively in each phase. This segmentation allows the system to capture complete perfusion processes at high velocities without overwhelming the computing system, as only relevant phase data is processed and stored for diagnostic analysis
Solution Approach 2:
The system performs preliminary actions by pre-configuring imaging parameters, selecting regions of interest (ROIs), and preparing processing algorithms before the actual contrast enhancement occurs. This preliminary preparation enables the system to rapidly process high-velocity imaging data during the actual perfusion capture without exceeding computing power limits
2Speed
If imaging velocity is increased to meet real-time observation requirements, then observation capability is improved, but imaging parameters must be adjusted reducing data quality
Solution Approach 1:
The patent implements dynamic adjustment of imaging parameters based on the selected contrast phase and imaging velocity requirements. The system dynamically optimizes parameters such as pulse repetition frequency, gain settings, and ROI boundaries to maintain measurement precision while achieving the required imaging velocities for real-time observation
Solution Approach 2:
The system changes imaging parameters according to the specific contrast phase being captured (arterial, venous, delayed) and the desired imaging velocity. By adapting parameters like transmission power, reception gain, and processing algorithms to match the imaging conditions, the system maintains data quality while achieving high-speed imaging
3Loss of information
If complete perfusion process data is captured at high velocity, then diagnostic information completeness is improved, but data volume increases requiring more storage and processing
Solution Approach 1:
The patent extracts and isolates only the most diagnostically relevant information from the high-velocity imaging data by focusing on specific contrast phases and regions of interest. This extraction process captures complete perfusion information needed for diagnosis while significantly reducing the overall data volume that requires storage and processing
Solution Approach 2:
The system performs preliminary data filtering and selection before full processing by pre-defining regions of interest and contrast phase windows. This preliminary action identifies and isolates the essential perfusion data early in the workflow, reducing the volume of data that needs to be fully processed and stored while maintaining complete diagnostic information
