Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic window processing is executed to calculate window values using image analysis processing, then the operator's manual work is reduced, but the processed window values may be changed by users requiring re-editing, which increases time and labor
Solution Approach 1:
The system establishes a linkage between reconstruction parameter changes and window value adjustments. When reconstruction parameters are modified, the system automatically detects this change and triggers recalculation of window values through image analysis processing, providing feedback control that prevents the need for manual re-editing
Solution Approach 2:
The system performs preliminary calculation of window values based on reconstruction parameters before actual image display. By pre-calculating appropriate window values linked to reconstruction parameters, the system prepares optimal display settings in advance, avoiding the need for operators to manually adjust window values after reconstruction parameter changes
2Adaptability or versatility
If multiple tomosynthesis images are generated with different reconstruction methods and filters, then diagnostic options are increased, but the complexity of tone conversion processing and parameter management increases
Solution Approach 1:
The system implements a universal tone conversion processing mechanism that automatically adapts to different reconstruction methods and filters. The same image analysis processing and window value calculation system handles multiple reconstruction types (FBP, AOP, etc.) and various filters, eliminating the need for separate processing chains for each reconstruction option
Solution Approach 2:
The system automatically adjusts tone conversion parameters based on the selected reconstruction method and filter settings. By dynamically changing window values, window levels, and other tone conversion parameters according to reconstruction parameters, the system simplifies the complexity of managing multiple reconstruction options while maintaining optimal image quality for each
