Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current magnetic resonance (MR) scanning technologies face challenges in setting appropriate scanning parameters for patients with multiple implants, as existing safety limit values can be too stringent, leading to suboptimal image quality or safety issues during scanning.
Innovation Solution
A scanning method and system that utilize a numerical distribution map from the MR system to determine an implant-related sensitive region, adjust scanning parameter limit values based on this information, and perform the scan with the adjusted parameters to balance image quality and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If safety limit values for scanning parameters are strictly followed, then patient safety is ensured, but image quality deteriorates
Solution Approach 1:
The patent applies local quality by differentiating safety limit values based on the specific location and type of implant within the patient's body. Instead of using a single uniform safety limit for all implants, the system determines implant information including location and type, then selects appropriate scanning parameter limits tailored to each specific implant scenario, allowing optimized image quality while maintaining safety
Solution Approach 2:
The patent implements dynamics by making scanning parameter limits adjustable and adaptive rather than fixed. The system dynamically adjusts safety limit values based on real-time determination of implant information, enabling the scanning parameters to vary according to specific clinical scenarios while maintaining safety standards
2Manufacturing precision
If safety limit values are lowered to improve image quality, then diagnostic accuracy improves, but safety risks increase
Solution Approach 1:
The patent applies feedback by incorporating a determination module that continuously monitors implant information and provides feedback on appropriate safety limit values. The system uses this feedback to dynamically adjust scanning parameters, ensuring that safety risks are minimized while maintaining sufficient image quality through data-driven parameter selection
Solution Approach 2:
The patent implements parameter changes by varying scanning parameter limits based on different implant characteristics. The system changes safety limit values according to the determined implant information, allowing optimized parameter selection for each specific implant type and location while maintaining safety through systematic parameter adjustment
3Manufacturing precision
If scanning parameters are optimized for specific implant types, then image quality improves, but system complexity increases
Solution Approach 1:
The patent applies universality by creating a multi-functional scanning system that can handle multiple implant types and locations through a single integrated framework. The determination module universally processes different implant information and the scanning module adaptively applies appropriate parameters, eliminating the need for separate protocols for each implant type while maintaining optimized image quality
Solution Approach 2:
The patent uses copying by creating a standardized implant information database and determination module that can replicate and reproduce appropriate scanning parameter selections for different implant scenarios. This copying approach allows the system to efficiently handle diverse implant types by referencing pre-established parameter patterns rather than requiring complex real-time calculations
4Adaptability or versatility
If physicians manually select scanning parameters for patients with multiple implants, then flexibility is maintained, but time consumption increases
Solution Approach 1:
The patent applies self-service by enabling the scanning system to automatically determine appropriate parameters based on implant information without requiring extensive manual intervention from physicians. The determination module autonomously processes implant data and selects scanning parameters, significantly reducing the time physicians would otherwise need to spend on parameter selection while maintaining clinical flexibility
Solution Approach 2:
The patent implements preliminary action by pre-establishing a comprehensive database of implant information and corresponding optimal scanning parameters. This preliminary preparation allows the system to quickly retrieve and apply appropriate parameters for patients with multiple implants without requiring time-consuming manual analysis during the actual scanning process
