Medical Image Display with Reference Value Color Coding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical imaging technologies face challenges in distinguishing between normal and abnormal measured values without clear reference, making it difficult for users to determine whether a measured value falls within a normal or abnormal range.
Innovation Solution
A method and apparatus that acquire measurement item information, determine reference values, and display additional information including the measured values on medical images, using color allocation and real-time measurement capabilities to indicate whether the measured values are within normal or abnormal ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If measured values are displayed without reference values, then the display is simple and clear, but users cannot determine whether the measured values are within normal or abnormal ranges
Solution Approach 1:
The patent introduces reference values as an intermediary element between the measured values and the user's judgment. The reference values serve as a mediator that enables users to compare and determine whether measured values are normal or abnormal, without requiring users to have prior knowledge of normal ranges.
Solution Approach 2:
The patent applies preliminary action by pre-calculating and displaying reference values before the user needs to make a judgment. The reference values are computed in advance based on stored reference data corresponding to the measured parameters, so that when measurements are taken, users can immediately compare against pre-prepared reference values without delay.
2Ease of operation
If reference values are displayed together with measured values, then users can easily determine normal or abnormal ranges, but the display complexity increases
Solution Approach 1:
The patent applies local quality by selectively displaying reference values only for specific measurement parameters that require reference comparison, rather than uniformly displaying all possible reference information. The system determines which parameters need reference values based on the measurement being performed, and displays only those relevant reference values, thus reducing unnecessary display complexity.
Solution Approach 2:
The patent segments the display information by separating measured values from reference values and presenting them in distinct formats or locations. This segmentation allows users to clearly distinguish between actual measurements and reference standards, reducing cognitive load and making the display easier to interpret despite containing multiple data elements.
3Loss of information
If multiple types of information are displayed together, then comprehensive diagnostic information is provided, but the information becomes difficult to distinguish and interpret
Solution Approach 1:
The patent employs color changes to differentiate between various types of information displayed together. Different colors are assigned to measured values, reference values, and other diagnostic information, enabling users to quickly distinguish between information types and understand their relative relationships through visual cues rather than relying solely on textual or numerical differentiation.

AI summary
Provided is a method of displaying additional information related to a measured value of an object, which includes acquiring measurement item information of the object; acquiring at least one of a measurement point and a measurement direction for the object; determining a reference value for a measurement based on the acquired measurement item information; acquiring the measured value of the object based on the at least one of the measurement point and the measurement direction; and displaying additional information including the determined reference value and the acquired measured value.
