Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an optical imaging apparatus is used to assist registration, then registration accuracy is improved, but the complexity of the radiographing system increases
Solution Approach 1:
An optical imaging apparatus is introduced as an intermediary device to capture optical images of the subject, which then serve as input data for the estimation unit to determine registration status. This mediator enables automated registration verification without requiring direct complex interactions between the radiographing apparatus and the subject positioning system.
Solution Approach 2:
The patent replaces manual registration verification with an automated image processing system. The estimation unit uses computational methods to analyze optical images and determine registration status, substituting mechanical registration adjustment procedures with automated digital image analysis and processing.
2Reliability
If automated estimation of subject information is performed, then registration reliability is improved, but the computational time and processing resources increase
Solution Approach 1:
The system performs preliminary image acquisition and estimation processing before the actual radiographic imaging. By pre-processing the optical images and determining registration status in advance, the system ensures reliable registration verification without delaying the main imaging process, as the estimation unit can work in parallel or beforehand.
Solution Approach 2:
The estimation unit automatically analyzes optical images to determine registration status without requiring manual intervention. The system self-verifies registration accuracy through automated image processing, reducing the need for operator involvement and minimizing time loss while maintaining high reliability.
3Measurement precision
If detailed analysis of optical images is performed, then the accuracy of registration verification is improved, but the complexity of image processing increases
Solution Approach 1:
The image processing task is segmented into distinct functional units: the first acquisition unit captures optical images, the estimation unit extracts subject information, and the determination unit verifies registration status. This segmentation allows each unit to perform specific processing functions independently, reducing overall processing complexity while maintaining high verification accuracy through specialized processing at each stage.
