Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If duplex systems are used for vascular mapping, then blood flow information resolution is improved, but system cost and complexity increase
Solution Approach 1:
The ultrasound system is designed to perform multiple functions using a single platform. The non-duplex ultrasound system integrates vascular mapping capabilities with standard ultrasound imaging, allowing the same system to perform both general imaging and specialized vascular assessment through software processing and advanced signal analysis techniques
Solution Approach 2:
The system changes operational parameters to achieve high-resolution blood flow measurement without requiring duplex technology. By adjusting ultrasound frequency, pulse repetition frequency, and signal processing parameters, the system optimizes Doppler measurements for vascular mapping applications while maintaining compatibility with standard ultrasound equipment
2Device complexity
If non-duplex ultrasound systems are used, then system cost is reduced, but blood flow information resolution deteriorates
Solution Approach 1:
The system replaces the need for complex mechanical duplex system components with advanced signal processing and computational methods. By using sophisticated algorithms to extract blood flow information from standard ultrasound signals, the system achieves high measurement precision without requiring expensive duplex hardware
Solution Approach 2:
The system creates virtual representations of blood flow characteristics through computational modeling and signal processing. By generating synthetic Doppler waveforms and flow velocity profiles from standard ultrasound data, the system replicates the measurement capabilities of duplex systems through software-based copying of the measurement process
