MRI Recording Region Cube Adjustment and Data Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In magnetic resonance imaging, users face challenges in selecting a cube-shaped recording region, which is often required for specific sequences, and this can lead to difficulties in defining the correct region, especially for body parts with varying dimensions, resulting in potential issues with image quality and artifacts.
Innovation Solution
The method involves automatically adjusting a user-defined cuboidal recording region to a cube-shaped one, ensuring that magnetic resonance scan data are acquired from a larger cube-shaped region, which is then processed to provide only the relevant image region of interest, enhancing user convenience and image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user manually defines a cuboidal recording region, then the user can specify the region of interest, but the user must worry about defining a cube-shaped region which is difficult for body parts with varying dimensions
Solution Approach 1:
The system automatically adjusts the user-defined cuboidal recording region to a cube-shaped second recording region by extending the region in one or more directions. This self-service mechanism eliminates the need for users to manually define complex cube-shaped regions, allowing them to simply specify the region of interest while the system handles the geometric transformation automatically.
2Reliability
If magnetic resonance scan data are acquired from a larger cube-shaped region, then the signal-to-noise ratio is improved, but the data volume increases
Solution Approach 1:
The acquired magnetic resonance scan data from the large cube-shaped second recording region are divided into multiple three-dimensional data sets. Each data set corresponds to a specific anatomical structure or region and can be processed and evaluated independently. This segmentation reduces the computational burden on individual data sets while maintaining the benefits of acquiring data from the larger cube-shaped region.
3Productivity
If only the relevant image region is provided from the acquired data, then the diagnostic efficiency is enhanced, but additional processing steps are required
Solution Approach 1:
The system automatically performs preliminary processing to identify and extract the relevant image region from the acquired magnetic resonance scan data before presenting it to the user. This preliminary action includes automatic segmentation, reconstruction, and selection of diagnostically relevant data, eliminating the need for users to manually process large volumes of raw data and significantly enhancing diagnostic efficiency.

AI summary
In a method and apparatus for magnetic resonance imaging of an examination object, a control computer is provided with a designation of a first recording region, which is cuboidal. The computer automatically determines a second recording region that represents an adjustment of the first recording region such that the second recording region is cube-shaped. Magnetic resonance scan data are acquired from the entire second recording region. Magnetic resonance image data are reconstructed from the acquired magnetic resonance scan data. An image region of the magnetic resonance image data is supplied in electronic form from the computer.
