MRI Planning Interface with Magnification Indicator for Protocol Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current magnetic resonance examination planning methods often result in image sections that are too small, leading to unclear visualization of graphic protocol objects, which can cause diagnostically irrelevant image data acquisition and repeated examinations.
Innovation Solution
A method where a planning image is displayed with a section of the patient's body to be examined, with graphic protocol objects superimposed, and relative size information is provided to indicate if the objects are fully or partially within the section, allowing for adjustment of the section size to match the objects, thereby enhancing clarity and reducing unnecessary data acquisition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a small section of the planning image is displayed to show detailed protocol objects, then the visualization of protocol objects is improved, but the user cannot see if slices are located outside the relevant section
Solution Approach 1:
The patent introduces a magnification indicator as an intermediary element that mediates between the detailed view and the complete overview. This indicator visually represents the relationship between the displayed section and the full planning image, providing information about slice locations outside the current view without requiring the user to switch between multiple displays or mentally map positions.
2Measurement precision
If the section size is kept small for detailed viewing, then protocol object details are visible, but diagnostically irrelevant image data may be acquired
Solution Approach 1:
The magnification indicator provides continuous feedback to the user about the relationship between the displayed section and the complete planning image. This feedback mechanism allows users to make informed decisions about protocol planning by showing them which areas are included in the current view and which areas may require adjustment, thereby preventing acquisition of diagnostically irrelevant data.
3Loss of information
If the section size is increased to show more area, then slice location context is provided, but protocol object visualization becomes less clear
Solution Approach 1:
The patent adds a visual dimension through the magnification indicator that encodes spatial relationship information. Instead of requiring the user to view the entire planning image to understand slice locations, the indicator provides this information in an additional visual layer, allowing detailed protocol object visualization to be maintained while simultaneously conveying contextual location information.

AI summary
In a method and magnetic resonance apparatus to support planning of a magnetic resonance examination on a patient with the magnetic resonance apparatus, a planning image is displayed and at least one graphic protocol object is superimposed thereon for a user. Information is thereby shown to the user as to whether at least one graphic protocol object is displayed outside the section of the planning image.
