Automatic MR Scan Template Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The creation of MR scan templates for magnetic resonance apparatuses is complex, making it difficult for users to customize templates to meet individual needs, leading to underutilization of pre-configured templates and limited creation of new ones due to the complexity of parameters and dependencies.
Innovation Solution
A method where the magnetic resonance apparatus automatically creates MR scan templates by detecting and storing parameters and properties of imaging sequences, allowing users to configure scans using parameter maps, and simulating scans to ensure quality, thereby simplifying the creation process and enabling automatic template generation based on acquired data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If MR scan templates are pre-configured by the manufacturer with multiple parameters and dependencies, then the templates can provide comprehensive scan coverage, but the complexity of creation and adjustment becomes too high for users
Solution Approach 1:
The system automatically generates MR scan templates by detecting parameters from actual scan acquisitions and storing them as reusable templates. This self-service mechanism eliminates the need for manual template creation and complex configuration, allowing the system to serve itself in creating optimized templates based on real-world usage patterns
Solution Approach 2:
The system creates templates by copying and storing parameter sets from successfully executed MR scans. Instead of manually designing templates from scratch, the system replicates working scan configurations and stores them as templates, simplifying the creation process while maintaining effectiveness
2Adaptability or versatility
If administrators manually adjust MR scan templates to meet individual user needs, then the templates can be customized, but the adjustment process becomes too complex and time-consuming
Solution Approach 1:
The system automatically adapts templates by detecting parameters from actual scan acquisitions and generating customized templates without requiring administrator intervention. This self-service approach eliminates time-consuming manual adjustments while maintaining individualized customization
Solution Approach 2:
The system uses feedback from actual scan acquisitions to automatically adjust and refine templates. By detecting parameters from real scan executions and using this information to generate improved templates, the system continuously optimizes without manual intervention
3Measurement precision
If the system stores detailed parameters of acquired MR scans for template creation, then accurate template generation is enabled, but the data storage and processing requirements increase
Solution Approach 1:
The system extracts only the essential parameters needed for template creation from the complete scan data. By selectively storing only the relevant parameter sets required for template generation rather than all scan data, the system maintains accuracy while reducing storage requirements

AI summary
In a magnetic resonance (MR) apparatus and operating method, an MR scan is designated in a processor by acquiring values of parameters of imaging sequences of the MR scan. The MR scan and properties of the MR scan are stored so as to be allocated to an MR scan template. The acquisition of an MR scan and the storing of an MR scan template are carried out several times. In the processor, one of the MR scan templates is determined by detecting properties of an MR scan to be performed and determining the MR scan template as a function of the properties. Imaging sequences of the determined MR scan template are then implemented in order to acquire MR data.
