MRI Parameter Grouping and Copying for Error Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current magnetic resonance imaging (MRI) apparatuses have a limited and inconvenient copy function for parameter settings, leading to increased time and risk of errors when copying or avoiding the copying of specific parameters between imaging operations.
Innovation Solution
A magnetic resonance imaging apparatus with a parameter storage unit that groups parameter types by imaging conditions and a controller to specify series and groups for efficient parameter copying and application, allowing for quick and accurate setting of imaging conditions by reading and applying parameter values from stored groups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If parameters are manually set for each imaging operation, then parameter values can be precisely controlled, but time required for parameter settings increases and risk of erroneous settings increases
Solution Approach 1:
The system copies parameter values from a previously set imaging operation to a new imaging operation. The controller reads parameter values from storage and automatically applies them to the new operation, eliminating manual re-entry and reducing errors while saving time.
Solution Approach 2:
Parameter values are set and stored in advance during a first imaging operation. The system prepares these parameter values for future use, so that when a second imaging operation is initiated, the parameters are already available for copying without requiring new manual input.
2Productivity
If a limited copy function is provided for specific parameter types, then copying time is reduced, but flexibility to copy any desired parameter is lost
Solution Approach 1:
The system provides a universal copy function that can copy any parameter value regardless of parameter type. The controller is designed to read and copy any parameter stored in the parameter storage unit, making the system adaptable to different imaging scenarios without being restricted to pre-defined parameter categories.
Solution Approach 2:
The system implements a flexible copying mechanism where any parameter value can be selected and copied from the storage unit to a new imaging operation. This allows users to copy only the specific parameters they need while maintaining high speed through automated processes.
3Adaptability or versatility
If all parameter types are registered for copying in advance, then any parameter can be copied, but unwanted parameters may be automatically copied and time is spent on registration
Solution Approach 1:
The system extracts only the specific parameter values that need to be copied from the full set of available parameters. Users can selectively choose which parameters to copy from the storage unit, rather than having all parameters automatically copied. This eliminates the need to register parameter types in advance while avoiding unwanted parameter copying.
Solution Approach 2:
The system allows users to independently select and copy only the parameters they need without requiring pre-registration or system configuration. The parameter storage unit stores all parameter values, and the user interface enables direct selection and copying of desired parameters without additional setup steps.
