Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional mammography imaging is used, then breast cancer screening can be performed, but the images are difficult to evaluate and lead to unclear results
Solution Approach 1:
The breast is segmented into multiple subvolumes using a predefined raster that divides the breast into several regions. This segmentation allows complex breast tissue to be broken down into manageable subregions, each with its own parameters, making the overall assessment more systematic and clearer.
Solution Approach 2:
The invention transitions from traditional 2D mammographic images to a 3D parameter map representation. By adding the spatial dimension and organizing data into a three-dimensional breast model with multiple subvolumes, the complexity is reduced while maintaining comprehensive information, making evaluation easier.
2Loss of information
If comprehensive breast imaging data is acquired, then more information is available for assessment, but the data becomes more complex and difficult to handle
Solution Approach 1:
Comprehensive breast imaging data is segmented into multiple subvolumes according to a predefined raster. Each subvolume contains specific parameters (density, glandular volume, etc.), organizing the complex data into structured, manageable units that are easier to handle while preserving complete information.
Solution Approach 2:
Different parameters are assigned to different subvolumes based on their specific characteristics. Each region receives the appropriate parameters for its local tissue composition, allowing comprehensive data to be maintained while simplifying processing through localized parameter assignment.
3Reliability
If standardized parameter mapping is implemented, then reporting can be standardized and longitudinal tracking enabled, but the system complexity increases
Solution Approach 1:
The predefined raster and parameter map system serves multiple functions: it enables standardized reporting, facilitates longitudinal tracking, supports epidemiological studies, and provides consistent parameter mapping across different imaging modalities. This multi-functionality achieves reliable standardized reporting without requiring separate systems for each purpose.
