Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated analysis is performed using scan parameters and metadata, then analysis efficiency is improved, but errors in scan parameters or metadata can lead to incorrect analysis results
Solution Approach 1:
The system performs preliminary consistency checking of scan parameters and metadata before the automated analysis is executed. By validating the input data in advance and detecting potential errors or inconsistencies prior to analysis, the system ensures that only reliable data is processed, thereby maintaining high analysis accuracy while preserving automated analysis efficiency.
2Reliability
If manual checking of scan parameters and metadata is performed, then error detection is improved, but time consumption increases
Solution Approach 1:
The system performs self-checking of scan parameters and metadata through automated consistency validation. The system independently verifies the correctness and consistency of its own input data without requiring manual intervention, thereby achieving reliable error detection while minimizing time consumption associated with manual checking.
Solution Approach 2:
The system implements automated feedback mechanisms that continuously monitor and validate scan parameters and metadata. By providing real-time feedback on data consistency and quality, the system enables automatic correction or rejection of erroneous data, achieving reliable error detection without the time overhead of manual verification processes.
3Manufacturing precision
If consistency checking is performed before image acquisition, then image quality is improved, but acquisition time is delayed
Solution Approach 1:
The system performs consistency checking of scan parameters and metadata as a preliminary action before image acquisition begins. By validating all input data in advance and obtaining corrections or confirmations prior to the actual scanning process, the system ensures high image quality while minimizing delays to the acquisition timeline.

AI summary
The invention provides for a medical imaging system (100) for acquiring medical image data (144) from an imaging zone (108). The medical imaging system comprises a memory (134) for storing machine executable instructions (140) and medical imaging system commands (142). The medical imaging system commands are configured for controlling the medical imaging system to acquire the medical image data according to a medical imaging protocol. The medical imaging system further comprises a user interface (132). The medical imaging system further comprises a processor (130) for controlling the medical imaging system. Execution of the machine executable instructions cause the processor to: receive (500) scan parameter data (146) for modifying the behavior of the medical imaging system commands; receive (502) metadata (148) descriptive of imaging conditions from the user interface; store (504) configuration data (150, 250, 252, 254) descriptive of a current configuration of the medical imaging system in the memory; calculate (506) an error probability (152) by comparing the metadata, the configuration data, and the scan parameter data using a predefined model (154), wherein the error probability is descriptive of a deviation between the metadata and between the configuration data and/or the scan parameter data; perform (508) a predefined action (158) if the error probability is above a predetermined threshold (156), wherein the predetermined action comprises providing a signal (302) to notify the user; control (510) the medical imaging system to acquire the medical image data from a subject (118); receive (512) a response (160) to the signal from the user interface in response to the signal; and reconstruct (514) one or more medical images (162) from the medical image data in accordance with the response.
