Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fixed image processing algorithms are used for all patients, then system simplicity is maintained, but image quality and abnormality detection are suboptimal for individual breast characteristics
Solution Approach 1:
The system automatically changes image processing parameters based on derived breast characteristics. Different algorithms and parameters are selected according to breast density, texture, and other characteristics, allowing optimization of image quality for each patient without manual intervention.
Solution Approach 2:
The system performs self-characterization by automatically deriving breast characteristics from the images themselves. The processing system uses the images to characterize the breast and then selects appropriate processing algorithms, making the system self-optimizing without requiring external input or manual parameter adjustment.
2Adaptability or versatility
If automated breast characterization is implemented, then image processing can be optimized for individual patients, but processing time and computational complexity increase
Solution Approach 1:
The system performs breast characterization in advance, using algorithms that quickly analyze image features to derive breast characteristics before the main image processing step. This preliminary characterization enables rapid selection of appropriate processing algorithms without significant time penalty.
Solution Approach 2:
The system uses feedback from the initial image analysis to guide the selection of processing algorithms. The derived breast characteristics provide feedback that automatically adjusts the processing parameters, creating an adaptive loop that optimizes both accuracy and efficiency.
3Measurement precision
If multiple image processing algorithms are applied to different breast regions, then localized image quality improves, but system complexity and processing difficulty increase
Solution Approach 1:
The system applies different image processing algorithms to different regions of the breast based on locally derived characteristics. Each region is characterized independently, and processing parameters are adjusted to match the specific breast characteristics of each region, optimizing image quality locally.
Solution Approach 2:
The breast image is segmented into multiple regions, and each region is processed independently with algorithms suited to its specific characteristics. This segmentation allows tailored processing for different tissue types and densities without requiring manual parameter selection for each region.
