Engineering Contradiction Analysis
1Measurement precision
If different arrangements of transmitting elements and receiving elements are used to increase spatial resolution, then imaging resolution is improved, but computational processing becomes complicated and processing delays increase
Solution Approach 1:
The patent segments the measurement data acquisition process by using a systematic arrangement of transmitting and receiving elements in parallel straight lines. This segmentation allows the complex imaging problem to be broken down into manageable computational steps, where data from different element combinations can be processed independently and then integrated, reducing overall computational complexity while maintaining high spatial resolution
Solution Approach 2:
The patent creates a universal imaging function that can process data from any combination of transmitting and receiving elements in the parallel array configuration. This multi-functional approach allows the same imaging algorithm to handle different measurement scenarios without requiring separate complex computations for each arrangement, thereby simplifying processing while achieving high resolution
2Measurement precision
If different arrangements of transmitting elements and receiving elements are used to increase spatial resolution, then imaging resolution is improved, but processing delays increase
Solution Approach 1:
The patent performs preliminary organization of measurement data according to the systematic parallel array configuration before actual imaging processing. By pre-structuring the data in accordance with the known geometric arrangement of elements, the patent eliminates the need for complex real-time computations during imaging, thereby reducing processing delays while maintaining high spatial resolution capability
3Measurement precision
If complex computational processing is used to image scatterer structure, then imaging accuracy is improved, but device complexity increases
Solution Approach 1:
The patent changes the parameter representation by using a coordinate system and mathematical model that directly corresponds to the physical parallel array configuration.
