Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If imaging parameters are set for multiple sequences in multistation imaging, then comprehensive image information is obtained, but the workload and complexity of parameter verification increases excessively
Solution Approach 1:
The patent performs parameter feasibility determination before actual imaging execution. The system checks whether imaging parameters are proper and whether images can be combined before the imaging process starts, allowing operators to identify and correct issues in advance without the burden of verifying multiple sequences manually after parameter setting.
2Manufacturing precision
If imaging parameters are changed to improve image quality, then image quality may be enhanced, but the risk of improper settings and combination failures increases
Solution Approach 1:
The patent implements a feedback mechanism where the system determines the feasibility of imaging parameters and displays results to operators. This feedback loop allows operators to verify parameter propriety and combination feasibility before execution, enabling informed adjustments while minimizing the risk of improper settings.
3Measurement precision
If manual verification of imaging parameters is performed for each sequence, then parameter accuracy may be ensured, but the time and operational load on operators increases significantly
Solution Approach 1:
The patent enables the system to automatically perform parameter feasibility determination and combination possibility assessment. The imaging managing unit determines whether imaging parameters are proper and whether images can be combined without requiring manual verification by operators, significantly reducing verification time while maintaining accuracy through automated checking.

AI summary
An object is to enhance usability of parameter check when an imaging parameter is changed in multistation imaging, and easily obtain a desired image with high quality. In the multistation imaging, it is determined in a lump before imaging whether an image having desired quality is obtained by using the changed value of the imaging parameter, and the result is presented to an operator. The determination is executed in the order of “possible or impossible” determination of execution of imaging itself and “possible or impossible” determination of combination of obtained images. When it is determined that it is impossible to execute the imaging itself, the determination processing is finished. At this time, a recommended value may be presented.
