Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an X-ray image processing system is configured for tumor imaging, then imaging capability is achieved, but device cost and complexity increase
Solution Approach 1:
The radiation beam treatment head is designed to perform both radiation therapy and imaging functions. The same radiation sources and detectors used for treatment can be utilized for imaging, eliminating the need for separate X-ray imaging systems and reducing overall system complexity
Solution Approach 2:
The imaging system is merged with the radiation therapy system by integrating detectors into the treatment head. The radiation beams serve dual purposes: treating the tumor and providing imaging data for real-time tracking and positioning
2Measurement precision
If an X-ray image processing system is configured for tumor imaging, then imaging capability is achieved, but device cost increases
Solution Approach 1:
The radiation beam treatment head is designed to perform both radiation therapy and imaging functions. The same radiation sources and detectors used for treatment can be utilized for imaging, eliminating the need for separate X-ray imaging systems and reducing overall system complexity
Solution Approach 2:
The radiation therapy system itself provides the imaging capability through its inherent radiation sources and integrated detectors, making the system self-sufficient for both treatment and imaging without requiring external expensive equipment
3Productivity
If multiple radiation sources are used for imaging, then real-time three-dimensional imaging is achieved, but system complexity increases
Solution Approach 1:
The treatment head is divided into multiple independent radiation source modules, each capable of emitting beams at different angles. This segmentation allows simultaneous multi-angle imaging while maintaining modular simplicity in each individual source unit
Solution Approach 2:
Multiple radiation sources are arranged in three-dimensional space around the treatment area, enabling real-time 3D imaging by capturing data from multiple spatial dimensions simultaneously rather than sequential 2D imaging
