Solution Overview
Problem
Current magnetic resonance diagnosing apparatuses fail to perform three-dimensional spectroscopy measurements effectively, as multi-slice imaging and spectroscopy are typically done separately, leading to situations where no slice image is available for diagnosis during MRS measurement.
Innovation Solution
A magnetic resonance diagnosing apparatus that generates multiple slice images and determines corresponding slice regions for spectroscopy, allowing for simultaneous measurement of magnetic resonance spectra and image generation at voxel positions, ensuring a slice image is always available for diagnosis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multi-slice imaging and spectroscopy measurement are performed separately, then the spectroscopy measurement can be carried out, but there is no slice image at a slice location within a slice region where the spectroscopy measurement was carried out
Solution Approach 1:
The patent combines multi-slice imaging and spectroscopy measurement into a unified process. The determining unit identifies slice regions for spectroscopy within the multi-slice imaging data, and the measurement unit performs spectroscopy measurement on voxels within those identified regions. This merging ensures that slice images are available at all slice locations where spectroscopy measurement is performed, eliminating the information loss problem while maintaining measurement precision.
2Productivity
If spectroscopy measurement and multi slice imaging are performed separately, then the spectroscopy measurement can be completed, but the diagnosis cannot be carried out while monitoring the slice image and MRS measurement result at the same time
Solution Approach 1:
The patent segments the spectroscopy measurement process by determining specific slice regions within the multi-slice imaging data. The determining unit divides the imaging data into distinct slice regions, and the measurement unit performs spectroscopy measurement on voxels within each determined region. This segmentation allows slice images to be available at each measured slice location, enabling real-time diagnostic monitoring without compromising measurement efficiency.
3Reliability
If slice regions for spectroscopy are determined within multi slice imaging region, then slice images are available at spectroscopy slice locations, but the system complexity increases
Solution Approach 1:
The patent implements multi-functionality within the magnetic resonance diagnosing apparatus. The determining unit serves multiple functions: it identifies slice regions for spectroscopy, ensures correspondence with multi-slice imaging locations, and enables both imaging and spectroscopy measurement capabilities. This universal approach ensures reliable slice image correspondence while avoiding the need for separate dedicated systems, thereby managing complexity effectively.
