Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple radiographic images are combined using fixed weights, then composite images with enhanced contrast and tissue emphasis can be generated, but the system lacks adaptability to user-specific diagnostic needs
Solution Approach 1:
The patent implements dynamic weight adjustment in the image processing system, allowing weights applied to multiple radiographic images to be modified based on user input. The controller receives user feedback and recalculates weights to generate customized composite images, transforming the system from static to dynamic and enabling adaptability to different diagnostic needs without requiring complete system redesign
Solution Approach 2:
The patent incorporates a feedback mechanism where user opinions or diagnostic requirements are received and used to adjust the weighting of multiple radiographic images. The controller processes this feedback and regenerates composite images with modified weights, creating a closed-loop system that continuously adapts to user needs while maintaining manageable complexity through iterative refinement
2Measurement precision
If multiple radiographic images are combined with customizable weights, then diagnostic accuracy is improved, but the operation time and processing complexity increase
Solution Approach 1:
The patent performs preliminary actions by acquiring multiple radiographic images of the same object with different imaging conditions (different X-ray tube voltages, currents, or exposure times) before the diagnostic process. These pre-acquired images are stored and can be quickly combined using adjusted weights when user feedback is received, reducing the time penalty of multiple image processing while maintaining diagnostic accuracy

AI summary
A radiographic imaging control method includes combining a plurality of images by applying a first weight to the plurality of images, displaying a composite image, acquired by combining the plurality of images, newly receiving a second weight with respect to the composite image, recombining the plurality of images based on the received second weight, and displaying a recombined image, acquired by recombining the plurality of images.
