MRI Scan Display Linking Body Movement to Cross-Section Progress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing MRI technologies fail to provide real-time feedback to users about the impact of subject movement on image quality during scanning, particularly when multiple cross-sectional images are involved, leading to potential artifacts and positional deviations that hinder accurate diagnosis.
Innovation Solution
An MRI apparatus that associates scan progress with body movement information, displaying this information in an intuitive manner to users, allowing them to quickly identify and respond to body movements affecting image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If body movement information is displayed in association with each independent scan, then it is possible to determine whether body movement equal to or greater than a predetermined threshold has occurred, but it is not possible to identify whether body movement affects a plurality of scans that are related to each other
Solution Approach 1:
The patent merges the display of body movement information with the display of scan information by superimposing body movement indicators onto the scan image display area. This integration allows users to simultaneously view scan images and identify body movement occurrences, enabling recognition of body movement effects across multiple related scans (axial, sagittal, coronal) without requiring separate independent displays for each scan type.
2Reliability
If body movement correction is performed as internal processing of the image diagnostic apparatus, then image quality can be improved, but it is not possible for users to know in real time at what point in time during imaging the body movement occurs
Solution Approach 1:
The patent implements a feedback mechanism by displaying body movement information in real-time during the scan process. Body movement indicators are superimposed on the scan image display area, providing immediate visual feedback to users about when and where body movement occurs. This allows users to understand real-time body movement timing and take appropriate actions, while the system continues to perform internal body movement correction processing to maintain image quality.
3Adaptability or versatility
If multiple cross-sectional images are acquired for the same imaging area, then comprehensive diagnosis can be performed, but artifacts and positional deviations occur when body movement happens during scanning
Solution Approach 1:
The patent segments the display interface into multiple independent display areas, with each area dedicated to displaying a specific scan type (axial, sagittal, coronal). Body movement indicators are selectively superimposed on the appropriate display area corresponding to the currently scanned section. This segmentation allows users to monitor body movement effects in each cross-sectional view independently, enabling identification of positional deviations and artifacts in specific planes while maintaining the ability to acquire comprehensive multi-planar images for diagnosis.

AI summary
For a scan task in which a plurality of cross-sectional images that are related to each other in imaging positions are imaged, a relationship between scans and body movements is presented to a user in an easily understandable manner.In a case where imaging including a plurality of scan tasks of cross sections is performed, progress of a scan and body movement information including a magnitude and an occurrence time of a body movement collected by a body movement processing unit are associated with each other, and on a display screen of a display device having a display region set to display at least one of the plurality of scan tasks, an image obtained in each scan, and the body movement information, the body movement information is displayed in association with the progress of the scan in the display region of the at least one.
