Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If 2D X-ray images are used for imaging, then the imaging process is simple and fast, but the discrimination between normal tissues and diseased tissues is limited
Solution Approach 1:
The patent transitions from 2D X-ray imaging to 3D tomosynthesis by introducing a temporal dimension through multiple angular views. The system captures images at different angles and reconstructs them into a 3D volume, enabling superior tissue discrimination while maintaining operational simplicity through automated reconstruction algorithms.
Solution Approach 2:
The system performs preliminary 3D volume reconstruction from multiple angular views before generating the final diagnostic images. This preliminary action creates a comprehensive 3D representation that enhances tissue discrimination capability in subsequent imaging steps.
2Measurement precision
If standard distance X-ray imaging is used, then the imaging geometry is simple, but the 3D effects are insufficient for accurate diagnosis
Solution Approach 1:
The patent creates virtual close-view images that are copies of the actual X-ray images but generated from a virtual perspective. By reconstructing images as if the X-ray source were positioned closer to the object, the system enhances 3D effects and diagnostic accuracy without requiring physical repositioning of imaging equipment.
Solution Approach 2:
The system introduces a virtual imaging geometry as an intermediary between the actual imaging setup and the final diagnostic output. This virtual close-view representation mediates the transformation of standard-distance images into enhanced 3D diagnostic images, improving accuracy without complicating the physical imaging system.
