Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two fluoroscopy apparatuses are used simultaneously for three-dimensional imaging, then imaging capability from multiple directions is improved, but radiation interference and scattered radiation increase causing degraded image quality
Solution Approach 1:
The patent implements periodic action by controlling the radiation sources to emit X-rays in alternating pulses rather than continuously. The control device coordinates the radiation sources so that one emits radiation while the other is off, creating a periodic emission pattern that eliminates scattered radiation interference while maintaining three-dimensional imaging capability.
Solution Approach 2:
The control device performs preliminary action by pre-coordinating the emission timing of multiple radiation sources before imaging begins. The system establishes a synchronized pulse emission schedule in advance, ensuring that radiation sources do not emit simultaneously, thereby preventing scattered radiation interference from the outset.
2Productivity
If radiation sources emit simultaneously from multiple fluoroscopy apparatuses, then imaging efficiency is improved, but scattered radiation from one apparatus interferes with detection in another apparatus
Solution Approach 1:
The system uses periodic pulsed emission where radiation sources alternate their emission in time. This maintains high imaging efficiency by keeping both apparatuses operational while ensuring that when one source emits, the other is off, preventing scattered radiation interference and maintaining image quality.
Solution Approach 2:
The control device ensures continuity of useful action by coordinating the pulsed emission of multiple radiation sources so that imaging continues without interruption. While one source is emitting, the other is preparing, creating a continuous imaging process that maintains efficiency while avoiding simultaneous emission interference.
3Object-affected harmful factors
If imaging timing is shifted between two fluoroscopy apparatuses, then scattered radiation interference is reduced, but the timing of X-ray irradiation cannot be properly set when one apparatus starts imaging after the other
Solution Approach 1:
The control device implements feedback by continuously monitoring the emission status of both radiation sources and dynamically adjusting the timing of each source based on the other's current state. This ensures that timing is always optimized to prevent scattered radiation interference, regardless of when imaging starts or stops on either apparatus.
Solution Approach 2:
The system applies dynamics by making the emission timing flexible and adaptive rather than fixed. The control device dynamically adjusts the pulsed emission timing of each radiation source based on real-time conditions, allowing seamless start and stop of imaging on either apparatus while maintaining optimal timing separation to prevent interference.

AI summary
A processor is configured to: register the fluoroscopy apparatus of which the processor controls the fluoroscopy and another fluoroscopy apparatus other than the fluoroscopy apparatus in association with each other; notify the other fluoroscopy apparatus of an imaging condition with the pulsed radiation in a case where an instruction to start emitting radiation is given in the fluoroscopy apparatus of which the imaging control device controls the fluoroscopy; and control, in a case where the imaging condition is notified from the other fluoroscopy apparatus in a case where the instruction to start emitting the radiation is not given in the fluoroscopy apparatus of which the imaging control device controls the fluoroscopy, and the instruction to start emitting the radiation is given, the fluoroscopy to emit the pulsed radiation, at timing at which the emission of the pulsed radiation is stopped in the other fluoroscopy apparatus based on the imaging condition.
