Dynamic Cross-Sectional Image Positioning for MRI Diagnostics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical image diagnosis systems, such as MRI and CT scanners, face challenges in accurately setting the location for cross-sectional images, particularly for complex structures like the heart, due to the need for precise three-dimensional data acquisition and generation of multiple intersecting images, which can be time-consuming and require operator intervention for correction.
Innovation Solution
An image processing apparatus and method that generates and displays first and second cross-sectional images, allowing for dynamic adjustment of their display locations based on changes in their intersecting location, utilizing a cross-section location deriver to calculate and update the positions of these images, facilitating easier operator correction and confirmation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If three-dimensional data is acquired and multiple cross-sectional images are generated to accurately set image taking locations, then measurement precision and manufacturing precision are improved, but loss of time and device complexity increase
Solution Approach 1:
The system performs preliminary acquisition of three-dimensional data and generation of auxiliary cross-sectional images before the actual imaging scan. This preliminary action allows the operator to pre-set the image taking location and verify spatial relationships, thereby improving location accuracy while reducing time during the actual diagnostic scan.
Solution Approach 2:
The auxiliary cross-sectional image serves as an intermediary tool that facilitates the setting of the basic cross-sectional image location. By displaying both the auxiliary image (from three-dimensional data) and the basic cross-sectional image (from actual scan) and allowing overlay or adjacent display, the system enables accurate location verification without requiring time-consuming iterative adjustments during the diagnostic procedure.
2Manufacturing precision
If multiple cross-sectional images are generated and displayed to verify image taking locations, then manufacturing precision is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The system merges the auxiliary cross-sectional image (derived from three-dimensional data) with the basic cross-sectional image (from actual imaging scan) by allowing them to be displayed overlaid or adjacent to each other. This merging enables the operator to verify location accuracy by comparing both images simultaneously, reducing the need for separate verification steps and simplifying the operation.
Solution Approach 2:
The system provides visual feedback by displaying both the auxiliary and basic cross-sectional images, allowing the operator to verify whether the image taking location is accurate. This feedback mechanism enables quick verification and correction without requiring complex manual adjustment procedures, thereby improving ease of operation while maintaining precision.
