Innovation Solution
A system that includes an X-ray source, detector, sensor, and controller to adjust radiation parameters and scan speed based on the weight of the person being inspected, ensuring adequate imaging quality while minimizing radiation dosage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If X-ray radiation with larger dosage is provided to ensure sufficient image definition for heavier persons, then imaging quality is improved, but radiation harm to lighter persons increases
Solution Approach 1:
The system dynamically adjusts the X-ray radiation dosage based on the detected weight of the person being inspected. The controller modifies radiation parameters in real-time according to weight measurements, transforming a static radiation dosage system into a dynamic one that adapts to individual needs, thereby resolving the contradiction between maintaining sufficient imaging quality and reducing unnecessary radiation exposure
Solution Approach 2:
The system changes the radiation dosage parameter based on the weight parameter of the inspected person. By establishing a relationship between weight and required radiation dosage, the system adjusts the X-ray radiation parameters (such as intensity or duration) to match the specific attenuation characteristics of different body weights, ensuring adequate imaging quality while minimizing radiation harm
2Ease of operation
If same dosage X-ray radiation is provided to all persons, then device operation is simplified, but imaging quality varies due to individual weight differences
Solution Approach 1:
The system performs preliminary weight detection before X-ray imaging to determine the appropriate radiation dosage in advance. By measuring the person's weight first and calculating the required dosage beforehand, the system prepares the optimal imaging parameters prior to actual scanning, ensuring consistent imaging quality without requiring complex real-time adjustments during the imaging process
Solution Approach 2:
The system uses weight measurement feedback to automatically adjust radiation dosage. The controller receives weight information from the detection device and uses this feedback to determine the appropriate X-ray radiation parameters, creating a closed-loop control system that maintains imaging quality consistency while keeping the operation process simple and automated
