Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image processing algorithms are used to reduce motion artifacts, then motion artifacts are reduced, but the workload and complexity increase significantly
Solution Approach 1:
The system performs preliminary action by guiding the patient to synchronize breathing before image acquisition. The breathing guidance apparatus prepares the patient in advance to maintain consistent breathing patterns, preventing motion artifacts before they occur rather than requiring complex post-processing algorithms to remove them.
Solution Approach 2:
The invention extracts and addresses the root cause of motion artifacts by isolating and controlling the breathing variable. By using the breathing guidance apparatus to standardize breathing patterns, the system removes the primary source of motion variation, allowing simpler image processing without compromising quality.
2Reliability
If complex processing algorithms are applied, then motion artifacts are reduced, but the data processing workload increases hugely
Solution Approach 1:
By guiding breathing synchronization before image acquisition, the system prevents motion artifacts from occurring in the first place. This preliminary control measure eliminates the need for computationally intensive post-processing algorithms, maintaining high image quality while preserving processing efficiency.
3Ease of operation
If breathing is not controlled, then the examination process is simple, but motion artifacts appear in the images
Solution Approach 1:
The breathing guidance apparatus serves as an intermediary device between the patient and the imaging system. It mediates the breathing control process by providing visual or auditory guidance signals, making it easy for patients to synchronize their breathing without requiring complex procedures or compromising image quality.
4Reliability
If breathing synchronization is implemented, then motion artifacts are reduced, but the device complexity increases
Solution Approach 1:
The breathing guidance apparatus acts as a simple intermediary that provides breathing synchronization signals to patients. This intermediate device enables motion artifact reduction through breathing control without requiring complex modifications to the core imaging system, thus limiting the increase in overall system complexity.
