Medical Image ROI Labels That Shift to Preserve Observation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical image processing systems interfere with user observation by superimposing class information related to a region of interest at its position, hindering the viewing of the region itself.
Innovation Solution
A medical image processing apparatus that superimposes class information at the position of a detected region of interest and changes its relative position over time to prevent interference, using methods such as moving the information away from the region or altering its display form.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If class information is superimposed at the position of the region of interest, then the information is intelligibly presented, but the user's observation of the region is interfered with
Solution Approach 1:
The patent applies the dynamics principle by making the display position of class information changeable over time. The class information is initially displayed at the position of the region of interest to provide clear information presentation, then automatically moved to a different position after a predetermined time period to eliminate observation interference. This temporal dynamic adjustment resolves the contradiction between information clarity and observation quality.
Solution Approach 2:
The patent implements periodic action through the time-based display strategy. Class information is displayed at the region of interest position for a specific duration (predetermined time period), then moved to another position. This periodic switching between different display positions ensures that the information is effectively communicated during the initial period while preventing continuous interference with user observation during subsequent periods.
2Reliability
If the region of interest is highlighted with a marker image, then the region is prevented from being overlooked, but the marker does not provide class classification information
Solution Approach 1:
The patent merges two separate functions into a single integrated display element. The class information (text or icon) serves both as classification identification and as a marker to highlight the region of interest. By combining the informational content with the marker function, the system simultaneously achieves reliable region detection and comprehensive class information presentation without requiring separate visual elements.
Solution Approach 2:
The displayed class information element performs multiple functions: it identifies the classification category of the region of interest, serves as a visual marker to highlight the detected region, and provides temporal dynamics to manage observation interference. This multi-functional design eliminates the need for separate marker images and class labels, efficiently resolving the information loss issue while maintaining detection reliability.

AI summary
In a medical image processing apparatus including a processor, the processor sequentially acquires time-series medical images and causes a display unit to sequentially display the acquired medical images. Further, the processor performs a process of acquiring, based on the acquired medical images, information related to a position of a region of interest in the medical images and classifying the region of interest into a class among a plurality of classes, and displays class information indicating the class of the classified region of interest such that the class information is superimposed at a position of the region of interest in a medical image displayed on the display unit. Further, the processor changes a relative position of the superimposed class information with respect to the region of interest, in accordance with an elapsed time from recognition of the region of interest.
