Retinal Tomographic Image Layer Boundary Editing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of editing layer boundaries in retinal tomographic images increases with improved image quality and analysis accuracy, making it difficult for examiners to correct layer positions efficiently.
Innovation Solution
An image processing apparatus that acquires tomographic images, allows for instruction-based changes in layer boundary positions, displays these changes overlapped on the image, and updates layer boundary information accordingly, facilitating easier editing by allowing multiple display forms and automatic adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of layer boundaries in the retinal tomographic image is increased to improve analysis accuracy and image quality, then the measurement precision and reliability are improved, but the device complexity and ease of operation deteriorate due to complicated editing operations
Solution Approach 1:
The patent segments the editing operation into two distinct modes: a first operation mode for selecting layer boundaries and a second operation mode for editing positions. This segmentation allows the system to handle multiple layer boundaries efficiently by providing mode-specific interfaces and controls, reducing the overall complexity of editing operations while maintaining high analysis accuracy
Solution Approach 2:
The patent implements dynamic switching between different operation modes based on the user's needs. The system can transition between the first operation mode (for selection) and the second operation mode (for editing), allowing flexible adaptation to different editing scenarios. This dynamic approach simplifies the editing process by providing context-appropriate controls for each mode
2Loss of information
If multiple layer boundaries are displayed in overlapped state to show all layer information, then the information completeness is improved, but the ease of operation deteriorates due to difficulty in distinguishing and editing individual boundaries
Solution Approach 1:
The patent applies local quality by displaying different visual characteristics for different layer boundaries within the overlapped display. Each layer boundary can be highlighted or distinguished using specific visual attributes (such as color, line style, or brightness) when selected or active, allowing examiners to easily identify and edit specific boundaries even when multiple boundaries are displayed simultaneously in an overlapped state
Solution Approach 2:
The system dynamically changes the display characteristics of layer boundaries based on the current operation mode and selection state. When a layer boundary is selected for editing, it is highlighted or emphasized visually, while other boundaries maintain their standard display appearance. This dynamic visual feedback helps examiners distinguish and edit individual boundaries efficiently
