Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous scanning is performed for long durations to obtain comprehensive imaging data, then imaging completeness is improved, but data management complexity and storage requirements increase excessively
Solution Approach 1:
The patent divides the continuous scanning process into discrete scanning layers, each producing independent raw data files. These files are then organized into file groups based on preset slicing rules (e.g., by anatomical region, scan time, or data type). This segmentation allows the system to manage large volumes of data through structured categorization, reducing data management complexity while preserving imaging completeness.
2Ease of operation
If raw data files are stored without organization to simplify storage, then storage ease is improved, but data retrieval speed and accuracy for image reconstruction deteriorate
Solution Approach 1:
The patent implements preliminary organization of raw data files into file groups during the scanning process itself. Preset slicing rules are applied in advance to categorize data before it needs to be retrieved for reconstruction. This preliminary action ensures that when data retrieval is needed, the system can quickly locate and access the required files without having to search through unorganized data, thus maintaining both storage ease and retrieval speed.
3Reliability
If scanning process is terminated unexpectedly to stop abnormal conditions, then system safety is improved, but previously acquired data is lost requiring restart
Solution Approach 1:
The patent segments the scanning process into discrete layers with independently stored raw data files. When scanning is terminated unexpectedly, only the current incomplete layer is affected, while previously completed layers and their associated data files remain intact and accessible. This segmentation prevents total data loss and allows the system to resume scanning from the interrupted point without discarding previously acquired data.
Solution Approach 2:
The system performs preliminary storage of completed scanning layers before the termination event occurs. By continuously organizing and storing finished data into file groups as scanning progresses, the system ensures that even if termination occurs mid-scan, all completed data is already securely stored and can be used for image reconstruction without requiring a complete restart.
4Measurement precision
If large raw data files are generated from long scans to maintain data quality, then imaging accuracy is improved, but processing time and storage capacity requirements increase
Solution Approach 1:
The patent segments large raw data files into smaller, organized file groups based on preset slicing rules. This segmentation allows the system to process and manage data in manageable chunks rather than handling monolithic large files, reducing processing time while maintaining the integrity and accuracy of the complete imaging data through proper organization and indexing.

AI summary
Disclosed is a method for data storage in magnetic resonance scanning, and a method and system for magnetic resonance scanning, which may include: detecting, during a scanning process, whether a protocol sequence suspending command is triggered; in response to determining that the protocol sequence suspending command is triggered, switching a scanning sequence from a scanning state to a suspending state; when the scanning sequence is in the suspending state, controlling the magnetic resonance device to stop scanning the target object and recording a completed scanning task and a raw data file corresponding to the completed scanning task; detecting whether the user activates the scanning sequence; and in response to determining that the scanning sequence is activated, determining an activation position of the scanning sequence based on a trigger state of the protocol sequence suspending command, and continuing to perform subsequent scanning of the scanning sequence based on the activation position.
