MRI Motion Correction Display With Reference Image Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing MRI technologies struggle with poor usability in body movement correction, as users cannot confirm whether automatically performed corrections are appropriate, and there is no clear indication of which slices require correction in multi-slice imaging.
Innovation Solution
Displaying a reference image or information about body movement correction alongside the corrected image, such as an original image, a reference image with different slice positions, or a difference image, to help users assess the appropriateness of the correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic body movement correction is performed without user settings, then usability is improved, but it becomes difficult to confirm whether the correction is appropriate
Solution Approach 1:
The system provides feedback to the user by displaying both the automatically corrected image and the original uncorrected image side by side. This visual feedback mechanism allows users to assess whether the automatic correction was appropriate without requiring manual intervention during the correction process, thus resolving the contradiction between ease of operation and information availability.
Solution Approach 2:
The system creates a copy of the original image (before correction) and displays it alongside the corrected image. This copy serves as a reference for users to evaluate the quality and appropriateness of the automatic correction, enabling users to verify correction results without re-performing the imaging process or manually adjusting parameters.
2Manufacturing precision
If body movement correction is applied to multi-slice imaging data, then image quality improves, but it becomes difficult to identify which slices require correction
Solution Approach 1:
The system uses visual differentiation (such as color coding, shading, or highlighting) to distinguish between slices that underwent body movement correction and those that did not. This visual encoding provides immediate slice identification information while maintaining the improved image quality of corrected slices, resolving the contradiction between precision and information availability.
Solution Approach 2:
The system segments the multi-slice imaging results into distinct visual groups, displaying corrected slices and uncorrected slices as separate, identifiable entities. This segmentation allows users to easily identify which slices require correction while preserving the quality benefits of correction for the appropriate slices.

AI summary
Provided is a technology for displaying information about automatically performed correction in a form in which a user can check the information while improving usability of body movement correction. In a case where an image subjected to body movement correction (body movement-corrected image) is displayed, a reference image for the image is also displayed. Alternatively, information regarding the body movement correction such as information indicating that the body movement-corrected image is the image subjected to the body movement correction, and a condition for the body movement correction, is also displayed. The reference image displayed together with the body movement-corrected image is, for example, any one or more images of an image (original image) reconstructed using the same measurement data without performing the body movement correction, an image (image without body movement correction) that has a different slice position or cross-sectional position captured consecutively to imaging of the body movement-corrected image, that does not require the body movement correction, and that is not subjected to the body movement correction, or difference image between the original image and the body movement-corrected image.
