MR Measurement Planning with Physical-Technical Limit Values
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of planning a magnetic resonance (MR) measurement sequence is hindered by numerous measurement parameters and parameter dependencies, making it difficult for users to establish valid values within physical-technical boundary conditions, leading to processing-intensive and time-consuming measurement planning processes.
Innovation Solution
A computer system with a user interface and processor configured to compute physical-technical limit values for selected measurement parameters, allowing for rapid establishment of valid values and preventing incorrect inputs, by transmitting control signals to an MR apparatus, and utilizing parameter dependencies to account for interactions between measurement parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users manually adjust multiple measurement parameters to fulfill physical-technical boundary conditions, then measurement planning flexibility is improved, but measurement planning time and complexity increase significantly
Solution Approach 1:
The system pre-calculates and stores valid parameter combinations and their interdependencies before the user needs them. When a user adjusts a parameter, the system has already prepared the consequences and valid ranges, enabling immediate feedback without time-consuming calculations during the planning phase.
Solution Approach 2:
The system provides real-time feedback to users about the validity of parameter adjustments by checking against pre-calculated boundary conditions and parameter dependencies. This immediate feedback guides users toward valid configurations without requiring manual verification or iterative trial-and-error processes.
2Reliability
If supporting routines are executed to find valid values for measurement parameters, then measurement parameter validity is improved, but processing time and computational load increase
Solution Approach 1:
The system performs validity checks and boundary condition verifications in advance, storing the results for rapid retrieval. This eliminates the need for time-consuming supporting routines during interactive planning, as the validity information is already prepared and available immediately when users adjust parameters.
3Reliability
If the system provides comprehensive parameter dependency checking, then measurement sequence validity is improved, but user interface complexity and response time worsen
Solution Approach 1:
The system pre-calculates parameter dependencies and valid ranges before the user interacts with the interface. When users adjust parameters, the system immediately retrieves pre-computed validity information rather than performing complex checks in real-time, maintaining both comprehensive validation and responsive performance.
