Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If real-time feedback guidance is implemented to improve patient compliance and image quality, then imaging performance and image quality are improved, but device complexity and system requirements increase
Solution Approach 1:
The system continuously monitors patient position and behavior during imaging, compares it against target positioning rules, and provides real-time feedback through visual, audio, or tactile signals. This closed-loop feedback mechanism enables dynamic adjustment of patient behavior to maintain optimal positioning, directly improving image quality by reducing motion artifacts and positioning errors.
Solution Approach 2:
The system empowers patients to self-correct their positioning and behavior through intuitive real-time feedback signals. By providing immediate guidance on their own performance, patients can independently maintain target positions and follow imaging protocols without requiring constant external supervision, thereby improving compliance and image quality.
2Manufacturing precision
If repeated scans are performed due to insufficient patient cooperation, then image quality may be improved, but patient throughput and imaging efficiency decrease
Solution Approach 1:
Real-time feedback guidance prevents positioning errors and non-compliance from occurring in the first place by continuously monitoring and correcting patient behavior during the scan. This proactive approach eliminates the need for repeated scans due to insufficient cooperation, thereby maintaining both high image quality and efficient patient throughput.
Solution Approach 2:
The system establishes target positioning rules and provides guidance before and during the imaging procedure to ensure patient compliance from the outset. By preparing patients in advance and providing continuous guidance, the system prevents positioning errors that would require retakes, thus avoiding time loss and maintaining throughput.
3Manufacturing precision
If detailed positioning rules and real-time monitoring are implemented, then imaging performance is improved, but the time required for imaging procedures increases
Solution Approach 1:
The real-time feedback system operates continuously throughout the imaging procedure, providing ongoing guidance to maintain optimal positioning without requiring pauses or interruptions. This continuous monitoring and guidance ensures high imaging performance while avoiding time loss that would result from stopping the scan for corrections.
Solution Approach 2:
By providing immediate feedback on positioning accuracy, the system enables patients to self-correct in real-time without delaying the imaging process. The feedback loop operates seamlessly during the scan, maintaining both high performance and efficient timing by eliminating the need for retrospective corrections.

AI summary
A medical imaging system is operated by determining a positioning rule indicating, for a region of interest, a target position, wherein a deviation between an actual position and the target position can affect imaging performance; obtaining measurement data of the region of interest, from which the actual position of the region of interest is derivable; determining a current deviation between the actual position and the target position of the region of interest, by comparing the positioning rule with the obtained measurement data; generating imaging performance information indicating whether the current deviation between the actual position and the target position of the region of interest currently affects the imaging performance in terms of image quality and/or remaining imaging time, or is expected to affect the imaging performance in terms of quality and/or remaining imaging time; and providing the generated imaging performance information to be communicated to a subject to be imaged.
