Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single system is used for both fluoroscopy and general imaging, then device complexity is reduced, but imaging efficiency and operational flexibility deteriorate
Solution Approach 1:
The system is segmented into distinct fluoroscopy processing units and general imaging processing units, each optimized for their specific function. This allows independent optimization of each mode while maintaining overall system efficiency, resolving the contradiction between device simplicity and imaging efficiency.
Solution Approach 2:
The radiography system is designed with multi-functionality to handle both fluoroscopy and general imaging operations. By integrating multiple processing capabilities within a single system framework, the invention achieves operational flexibility and improved imaging efficiency without requiring entirely separate systems.
2Speed
If separate processors are used for fluoroscopy and general imaging, then image processing speed is improved, but device complexity increases
Solution Approach 1:
The processing system is divided into separate fluoroscopy processors and general imaging processors, allowing each to be optimized for its specific processing requirements. This segmentation enables faster, specialized processing for each mode while maintaining manageable system complexity through clear functional separation.
3Area of stationary object
If the irradiation area is increased to cover the entire detection surface, then imaging coverage is improved, but the ability to perform both fluoroscopy and general imaging with optimal conditions deteriorates
Solution Approach 1:
The collimator is designed with dynamic adjustment capabilities, allowing the irradiation area to be changed based on the imaging mode requirements. This enables the system to optimize the irradiation area for each specific mode (fluoroscopy or general imaging) rather than being fixed, thereby maintaining versatility and optimal performance for both modes.

AI summary
Provided are a radiography system, a radiography method, and a radiography program that can improve an imaging efficiency in a radiography system capable of executing fluoroscopy and general imaging in a switchable manner. A radiography system sets an imaging mode to a fluoroscopy mode in a case where a condition that an irradiation area of radiation on a detection surface of a radiation detector is equal to or less than a maximum area capable of detecting the radiation in the radiation detector is satisfied, and causes the radiation detector to start processing of continuously acquiring an image at a predetermined frame rate regardless of whether or not an instruction to start irradiation with the radiation is received in a case where the imaging mode is the fluoroscopy mode.
