Automated MR Sequence Parameter Modification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional MR measurement techniques are prone to errors when repeating scans with slightly modified parameters, leading to inconsistent data due to manual adjustments and loss of parameter relationships during software updates.
Innovation Solution
An automated method for creating and managing modified imaging sequences in an MR apparatus, where a second set of imaging parameters is created with only specific parameters modified, ensuring all other parameters remain unchanged, and these sequences are stored in a measuring queue to maintain consistency across measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual adjustment of imaging parameters is used for repeating scans, then flexibility in modifying parameters is achieved, but operator errors and inconsistency increase
Solution Approach 1:
The system automatically copies the imaging sequence and modifies parameters without requiring manual operator intervention. The control computer autonomously manages the repetition of scans with modified parameters, eliminating human error while maintaining flexibility through automated parameter adjustment capabilities.
Solution Approach 2:
The imaging sequence is automatically copied and stored in the measuring queue with specified parameter modifications. This copying mechanism ensures exact reproduction of the original sequence while allowing controlled variations, thereby maintaining consistency and reducing errors associated with manual reconfiguration.
2Productivity
If imaging sequences are linked and stored in measuring queue, then automated execution is improved, but parameter consistency across different positions in queue deteriorates
Solution Approach 1:
The imaging sequence and its parameter settings are prepared and stored in advance in the measuring queue before execution. This preliminary configuration ensures that all sequences, regardless of their position in the queue, maintain consistent parameters as pre-defined, enabling automated execution without compromising parameter stability.
3Adaptability or versatility
If software version is updated, then system capabilities are improved, but relationship between imaging parameters is lost
Solution Approach 1:
The complete imaging sequence including all parameter relationships is copied and stored digitally. This digital copy preserves the interrelationships between parameters even when software versions are updated, as the parameter settings are retained in the stored sequence rather than being tied to the specific software version's default configurations.

AI summary
In a method for performing MR measurements in an MR system on an object, MR signals of the object are acquired using an imaging sequence with a first set of imaging parameters. An amended copy of the imaging sequence is automatically created with a second set of imaging parameters, which has all the imaging parameters used in the first set, wherein the second set has at least one imaging parameter modified with respect to the first set that differs from the corresponding imaging parameter of the first set according to a defined amendment. The remaining imaging parameters of the second set correspond to the imaging parameters of the first set. The amended copy is automatically configured in a measurement queue in which all the imaging sequences are stored that are to be carried out in the future on the examination object are stored.
