OCT Optic Disk and Macular Map Display for Overlap-Free Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing optical coherence tomography systems, analysis maps for the optic disk and macular area often overlap partially, making it inconvenient for examiners to diagnose as parts of the maps become invisible, hindering effective analysis and diagnosis.
Innovation Solution
The system performs analysis of both the optic disk and macular area on a single piece of three-dimensional data using optical coherence tomography and displays the resulting analysis maps side by side, along with a two-dimensional image of the region, preventing overlap and enhancing diagnostic convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If analysis maps for optic disk and macular area are displayed in a superimposed manner, then it is convenient to recognize the state over the widespread region of the fundus, but parts of the analysis maps become invisible due to overlap, hindering effective analysis and diagnosis
Solution Approach 1:
The patent divides the display area into multiple regions and places different analysis maps (optic disk analysis map and macular area analysis map) in separate, non-overlapping regions. This segmentation allows each analysis map to be fully visible without being obscured by others, while still presenting comprehensive fundus information in a single display screen.
2Loss of information
If analysis maps for optic disk and macular area are displayed side by side, then all information remains visible without overlap, but the convenience of recognizing the widespread region state is reduced
Solution Approach 1:
The patent transitions from a single superimposed two-dimensional display to a multi-region side-by-side two-dimensional layout. By strategically positioning analysis maps in different spatial regions of the display screen, the system maintains complete visibility of all information while preserving the ability to recognize the overall widespread fundus state through the coordinated arrangement of separate regions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach allows for clear visualization of both analysis maps without overlap, improving diagnostic efficiency and convenience for examiners by ensuring all information is readily accessible.
Implementation Method 1
obtains, using a coherence tomography, an analysis map for an optic disk and an analysis map for a macular area, which are analysis results of three-dimensional data obtained by capturing an image

AI summary
An apparatus includes an obtaining unit configured to obtain, using an optical coherence tomography, an analysis map for a disk and an analysis map for a macular area, which are analysis results of three-dimensional data obtained by capturing an image of a region of a fundus of a subject's eye that includes the disk and the macular area, and a control unit configured to cause a display unit to display side by side a two-dimensional image of the region including the disk and the macular area, the analysis map for the optic disk, and the analysis map for the macular area.
