Physiologically-derived map generation with frequency-based color coding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical imaging technologies face challenges in generating a simple and effective method to create a physiologically-derived map correlated with anatomical image data, which is essential for accurately representing physiological processes and conditions within examination areas.
Innovation Solution
A method involving a computer that determines the frequency of spatially resolved physiologically-derived values, selects a portion of the value range, assigns color coding to these values, and generates a physiologically-derived map by correlating the values with anatomical image data, allowing for a user-specific and high-resolution representation of physiological processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If color coding is assigned to the entire value range of physiologically-derived values, then the map covers all possible values, but the resolution and clarity for relevant values is reduced due to the limited color palette
Solution Approach 1:
The value range is segmented into a selected portion (for color coding) and values outside this portion (suppressed). This segmentation allows the limited color palette to be concentrated on the most relevant physiologically-derived values, improving resolution and clarity for diagnostically important ranges while maintaining adaptability to the full value range through selective suppression of less relevant values.
2Loss of information
If all physiologically-derived values are displayed in the map, then complete information is provided, but the map becomes complex and difficult to interpret clinically
Solution Approach 1:
Values outside the selected portion of the value range are extracted and suppressed from the color-coded display. This extraction removes irrelevant or less clinically significant values from the visual representation, simplifying the map interpretation while preserving the option to access complete information through the frequency determination step, which identifies which values fall into the selected portion.
3Manufacturing precision
If the selected portion of the value range is adjusted to focus on specific values, then the clarity for those values improves, but the coverage of other potentially relevant values is reduced
Solution Approach 1:
The selected portion of the value range is defined dynamically based on frequency determination. The computer determines the frequency of physiologically-derived values within the value range and selects the portion accordingly, allowing the range to adapt to the specific dataset being analyzed. This dynamic selection optimizes clarity for the most relevant values in each case while maintaining versatility through frequency-based adaptation.

AI summary
In a method and a computer for generating a physiologically-derived map correlated with anatomical image data spatially resolved physiologically-derived values within a value range are provided to a computer, as are anatomical image data. A frequency of occurrence of the provided physiologically-derived values is determined in the computer, depending on the occurrence of physiologically-derived values within the value range. A portion of the value range is selected in or via the computer, based on the determined frequency of the provided physiologically-derived values. Color coding is assigned in the computer to the physiologically-derived values of the value range outside the selected portion. A physiologically-derived map is generated by the computer by assigning a physiologically-derived value corresponding to the assigned color coding to its spatially resolved position in relation to the anatomical image data, and the map is shown at a display screen of the computer.
