Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual setting of calibration scan conditions is performed, then measurement precision is maintained, but ease of operation deteriorates
Solution Approach 1:
The system automatically determines calibration scan conditions by utilizing imaging scan parameters and coil element information already available in the system. The calibration scan condition determining device self-generates appropriate calibration conditions without requiring operator intervention, thereby maintaining measurement precision while significantly improving ease of operation
Solution Approach 2:
The system performs preliminary determination of calibration scan conditions based on pre-acquired imaging scan data and coil element configurations. By preparing calibration conditions in advance using already-available system parameters, the invention eliminates the need for manual operator input while ensuring accurate calibration settings are established before actual calibration execution
2Reliability
If calibration scan is performed each time imaging is executed, then reliability is improved, but loss of time increases
Solution Approach 1:
The system dynamically adjusts calibration scan parameters based on the specific imaging scan conditions and coil element combinations being used. By changing calibration parameters to match current imaging parameters, the system maintains high reliability for image correction while avoiding redundant calibration scans that would waste time
