Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple pulses are output at varying rates for image acquisition, then image quality and three-dimensional reconstruction precision are improved, but radiation exposure increases
Solution Approach 1:
The system employs periodic pulsed radiation output with varying pulse rates tailored to different imaging requirements. By using periodic action rather than continuous radiation, the system achieves necessary image quality while minimizing overall radiation exposure through strategic timing and duration of pulses.
Solution Approach 2:
The system dynamically changes radiation parameters including pulse rate, pulse duration, and pulse intensity based on the specific imaging needs. By adjusting these parameters, the system optimizes the balance between achieving sufficient image quality for accurate three-dimensional reconstruction and minimizing radiation exposure to the subject.
2Manufacturing precision
If multiple pulses are output for detailed image reconstruction, then manufacturing precision of image data is improved, but use of energy increases
Solution Approach 1:
The system uses periodic pulsed energy output instead of continuous energy consumption. By timing the energy pulses to coincide with specific imaging phases and using varying pulse rates, the system achieves detailed image reconstruction precision while significantly reducing overall energy consumption compared to continuous operation.
Solution Approach 2:
The system dynamically adjusts energy delivery parameters including pulse rate, pulse width, and pulse intensity based on the imaging stage and requirements. This parameter optimization allows the system to achieve high image data precision for three-dimensional reconstruction while minimizing total energy consumption through efficient pulse timing and duration control.
3Use of energy by moving object
If single pulse output is used, then energy consumption is reduced, but image data precision deteriorates
Solution Approach 1:
The system applies different pulse strategies to different regions or imaging stages based on local requirements. By using single pulses or reduced pulse sequences for regions requiring lower precision and full multi-pulse sequences only where high precision is critical, the system optimizes the balance between energy consumption and image data precision across the entire imaging volume.
4Productivity
If rapid pulse output is used for real-time imaging, then productivity is improved, but radiation exposure increases
Solution Approach 1:
The system employs rapid periodic pulsed radiation output synchronized with the imaging acquisition timing. By using high-frequency periodic pulses only during the brief windows when image data is being acquired and the subject is in the required position, the system achieves real-time imaging productivity while minimizing radiation exposure by not maintaining continuous high-rate pulsing.
Solution Approach 2:
The system dynamically adjusts the pulse rate based on real-time imaging conditions, subject position, and acquisition phase. By increasing pulse rate rapidly during critical imaging moments and reducing or pausing between acquisitions, the system achieves high productivity for real-time imaging while minimizing overall radiation exposure through adaptive timing control.
