Retinal Abnormality Visualization in OCT Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies struggle to effectively compare and visualize the relationship between abnormal regions detected from the shape of the retinal layer and those detected based on tomographic images.
Innovation Solution
An information processing apparatus that acquires tomographic images, shape abnormality information, and tomographic abnormality information, and displays them in a manner that distinguishes between the two types of abnormality information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If shape abnormality information and tomographic abnormality information are displayed together, then diagnostic accuracy is improved, but display complexity increases
Solution Approach 1:
The patent divides the display into separate regions: one region displays shape abnormality information (derived from shape maps showing retinal layer thickness variations) while another region displays tomographic abnormality information (derived from cross-sectional OCT images). This segmentation allows both types of abnormality information to be presented simultaneously without visual confusion, maintaining diagnostic accuracy while managing display complexity through spatial organization.
2Loss of information
If abnormal regions from different detection processes are visualized together, then relationship understanding is improved, but visualization complexity increases
Solution Approach 1:
The patent introduces an intermediary display structure that maps both shape-based abnormal regions and tomographic-based abnormal regions onto a common coordinate system representing the retinal surface. This intermediary visualization layer allows clinicians to understand the spatial relationship between abnormalities detected through different processes without directly complicating the underlying detection algorithms.
