Engineering Contradiction Analysis
1Illumination intensity
If X-ray captures are optimized for visual examination, then visual quality is improved, but suitability for subsequent processing and three-dimensional reconstruction is worsened
Solution Approach 1:
The system performs preliminary analysis of the first X-ray capture to determine the optimal second capture angle before actually capturing the second image. This advance planning ensures that the second capture is specifically optimized for three-dimensional reconstruction purposes, not just visual examination. The computing unit evaluates suitability of different capture angles and selects the best one in advance, making the subsequent capture process more targeted and effective.
Solution Approach 2:
The system changes the capture angle parameter based on the analysis results. Instead of using fixed or visually-optimized angles, the system dynamically adjusts the second capture angle to be specifically suitable for three-dimensional reconstruction. This parameter optimization ensures that the X-ray captures are tailored for their intended processing purpose, improving both the quality and suitability for subsequent analysis.
2Manufacturing precision
If additional captures are taken subsequently for optimized three-dimensional reconstruction, then quality of 3D model is improved, but burden on patient health increases
Solution Approach 1:
The system optimizes the capture angle parameter to achieve high-quality three-dimensional reconstruction with minimal additional captures. By calculating the optimal second capture angle based on the first capture analysis, the system reduces the need for multiple redundant captures, thereby minimizing radiation exposure to the patient while maintaining high reconstruction quality.
Solution Approach 2:
The system replaces manual operator experience-based capture selection with an automated computing unit that analyzes the first capture and calculates the optimal second capture angle. This automated system ensures scientifically optimal capture parameters are used, reducing the number of captures needed while achieving high-quality three-dimensional models, thus reducing patient radiation burden.
3Ease of operation
If capture angle selection is based on operator experience, then flexibility is improved, but reproducibility and consistency are worsened
Solution Approach 1:
The system performs self-analysis of the first X-ray capture and automatically determines the optimal second capture angle without relying on operator experience. The computing unit independently evaluates the capture data and makes decisions about the second capture parameters, ensuring consistent and reproducible results across different operators and cases while maintaining operational flexibility.
Solution Approach 2:
The system uses feedback from the first capture analysis to determine the second capture angle. By analyzing the results of the first capture and using that information to optimize the second capture parameters, the system creates a closed-loop process that ensures reproducibility and consistency while maintaining the ability to adapt to different anatomical variations.
