Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If tube voltage and mAs value are set according to imaging part and body thickness, then imaging precision is improved, but device complexity increases
Solution Approach 1:
The radiation emitting device automatically determines imaging part and body thickness information, then autonomously derives appropriate tube voltage and mAs values without requiring manual intervention. The device serves itself by using its own acquired data to set imaging parameters, thereby improving imaging precision while avoiding the complexity increase that would result from external manual control systems.
Solution Approach 2:
The system dynamically adjusts tube voltage and mAs values as parameters based on the acquired imaging part and body thickness information. By changing these parameters adaptively according to the specific imaging conditions, the system achieves precise imaging control without requiring complex fixed-parameter configurations or multiple dedicated devices for different imaging scenarios.
2Device complexity
If manual setting of tube voltage and mAs value is used, then device complexity is reduced, but imaging precision deteriorates
Solution Approach 1:
The radiation emitting device performs self-setting by automatically acquiring imaging part and body thickness information, then deriving appropriate tube voltage and mAs values. This eliminates the need for complex manual setting procedures while maintaining simple device architecture, simultaneously achieving both low device complexity and high imaging precision.
Solution Approach 2:
The system performs preliminary acquisition of imaging part and body thickness information before setting tube voltage and mAs values. By preparing the necessary data in advance through automatic acquisition, the system can directly derive optimal parameters without requiring complex real-time manual adjustment mechanisms, thus maintaining simplicity while improving precision.
3Ease of operation
If fixed imaging conditions are used, then ease of operation is improved, but adaptability deteriorates
Solution Approach 1:
The system transitions from fixed imaging conditions to dynamic parameter adjustment by automatically deriving tube voltage and mAs values based on acquired imaging part and body thickness information. This dynamic adaptation maintains ease of operation through automatic settings while significantly improving adaptability to different imaging scenarios, body types, and anatomical structures.
Solution Approach 2:
The imaging parameters are changed dynamically based on the specific imaging part and body thickness detected. Instead of using fixed conditions, the system adjusts tube voltage and mAs values as needed, achieving both operational simplicity through automation and high adaptability to varying imaging requirements without requiring manual reconfiguration.

AI summary
A setting device comprising at least one processor, wherein the processor is configured to: acquire imaging part information indicating an imaging part of a subject whose radiographic image is captured by radiation emitted from a radiation emitting device; acquire body thickness information indicating a body thickness of the subject in a direction in which the radiation is transmitted; acquire condition information indicating whether a tube voltage value and a mAs value are each set to variable or fixed; and derive a set value of the tube voltage and a set value of the mAs value of the radiation emitting device for emitting the radiation such that a dose of the radiation transmitted through the imaging part is the same as a dose at a reference body thickness, on the basis of the imaging part information, the body thickness information, and the condition information.
