Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real-time dose distribution display is implemented, then radiation exposure control precision is improved, but device complexity increases
Solution Approach 1:
The patent creates a virtual copy of the patient's anatomy using CT or MRI data to form a 3D model. This virtual model allows dose distribution to be calculated and displayed without requiring physical dosimeters on the patient, thereby improving measurement precision while avoiding the complexity of multiple physical sensing devices.
Solution Approach 2:
The patent replaces physical dosimetry systems with computational methods. Instead of using mechanical or physical dosimeters to measure radiation exposure, the system uses computer-based algorithms to calculate and simulate dose distributions on the 3D anatomical model, reducing device complexity while maintaining measurement precision.
2Object-affected harmful factors
If simulated dose distributions are generated and displayed, then patient radiation exposure is reduced, but information processing requirements increase
Solution Approach 1:
The patent performs dose distribution calculations and generates the 3D model before the actual X-ray examination. By preparing the anatomical model and calculating expected dose distributions in advance, the system allows operators to optimize examination parameters beforehand, thereby reducing patient exposure during the actual procedure while managing information processing efficiently through pre-computation.
3Productivity
If 3D model-based dose distribution visualization is implemented, then exposure optimization is improved, but data processing complexity increases
Solution Approach 1:
The patent uses a multi-functional 3D modeling system that serves multiple purposes: anatomical visualization, dose distribution calculation, and examination planning. This universal approach consolidates multiple data processing functions into a single integrated system, improving exposure optimization efficiency while managing data processing complexity through functional integration rather than separate specialized systems.
