Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional X-ray imaging techniques are used, then the imaging process is simple and fast, but the diagnostic accuracy is limited and critical information about tissue abnormalities is not provided
Solution Approach 1:
The patent segments the X-ray detection process into multiple energy bins, where photons are sorted by their energy levels. This allows different tissue types to be distinguished based on their differential absorption of X-rays at various energies, thereby improving diagnostic accuracy without requiring fundamentally new equipment
Solution Approach 2:
The patent adds an energy dimension to traditional X-ray imaging by measuring photon energy in addition to spatial position. This transforms the imaging from a 2D spatial representation to a 3D representation that includes energy information, enabling better tissue characterization and abnormality detection
2Loss of information
If conventional X-ray imaging techniques are used, then the system operation is straightforward, but the ability to distinguish between different tissue components is limited
Solution Approach 1:
The patent applies local quality by assigning different energy thresholds and binning strategies to different regions of the detector or different anatomical areas. This allows optimization of information extraction for specific tissue types or regions of interest while maintaining overall system functionality
Solution Approach 2:
The patent changes the detection parameter from simple photon counting to energy-resolved photon counting. By measuring and binning photons according to their energy levels, the system extracts additional information about tissue composition and density, reducing information loss about different tissue components
