MRI Planning Interface with 3D Survey Volume Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Planning cardiac examinations using MRI is challenging for both novice and experienced users due to the complexity of imaging anatomy, requiring a user-friendly method to define scanning steps and adjust imaging parameters efficiently.
Innovation Solution
An apparatus with a data acquisition module and a planning module that includes a user interface displaying predefined imaging parameters for each scanning step, allowing users to adjust parameters visually by manipulating lines representing the line of sight on a three-dimensional survey volume of the anatomy, enabling less experienced users to plan and execute examinations effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fully automatic calculation and determination of scanning parameters is used, then productivity is improved, but ease of operation deteriorates for novice users
Solution Approach 1:
The system introduces an intermediary visualization layer between automatic parameter calculation and user interaction. Instead of directly manipulating complex parameters, users interact with visual representations (lines on 3D survey volume) that automatically translate into scanning parameters. This mediator layer simplifies the interface while maintaining automated efficiency.
Solution Approach 2:
The system creates a visual copy or representation of the scanning geometry as lines on a 3D survey volume. Users manipulate these visual copies rather than the actual scanning parameters directly. The lines serve as visual proxies that automatically convert into the technical scanning parameters needed for image acquisition.
2Measurement precision
If complex anatomy imaging is required, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system transitions from 2D planar parameter adjustment to 3D spatial visualization. By displaying scanning parameters as lines on a three-dimensional survey volume, users can intuitively understand and adjust complex spatial relationships without dealing with multiple separate 2D parameter settings, thereby reducing perceived complexity while maintaining precision.
3Ease of operation
If default parameters are used for scanning, then ease of operation is improved, but adaptability to individual anatomy deteriorates
Solution Approach 1:
The system provides dynamic parameter adjustment where default parameters serve as a starting point that users can easily modify. The visual interface allows real-time adjustment of scanning parameters by manipulating lines on the 3D volume, enabling seamless transition from default to customized settings based on individual anatomy requirements.
