MRI Image Display for Verifying Body Movement Correction
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 or have undergone movement correction in multi-slice imaging.
Innovation Solution
The MRI apparatus displays a body movement-corrected image alongside a reference image or information about the correction, such as an original image, a slice image without correction, 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 the user cannot confirm whether the correction is appropriate
Solution Approach 1:
The patent implements feedback by displaying the original image alongside the body movement-corrected image. This allows users to verify whether the automatic correction is appropriate by directly comparing the corrected image with the original, providing visual feedback on the correction quality without requiring user settings for correction parameters.
Solution Approach 2:
The patent uses a copy of the original image displayed together with the corrected image. This copy enables users to assess the correction appropriateness by comparing the corrected image with its original version, maintaining usability while providing verification capability.
2Reliability
If body movement correction is applied to multi-slice imaging data, then image quality improves, but it becomes difficult to identify which slices require or have undergone correction
Solution Approach 1:
The patent applies different display characteristics (such as color coding or visual markers) to indicate which slices have undergone body movement correction. This allows users to easily identify corrected slices among multiple slices, maintaining image quality improvement while preserving information about correction status.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach enhances usability by allowing users to verify the effectiveness of body movement corrections and identify which slices have been corrected, improving the reliability of diagnostic images.
Implementation Method 1
an imaging unit that collects a nuclear magnetic resonance signal of a subject
Implementation Method 2
an image generation unit that reconstructs an image of the subject using k-space data consisting of the nuclear magnetic resonance signal collected by the imaging unit
Implementation Method 3
a body movement processing unit that analyzes a body movement of the subject during imaging
Implementation Method 4
the image subjected to the body movement correction includes at least one of an image corrected by body movement correction reconstruction or an image in which the body movement is corrected by re-measurement

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.
