Ophthalmic Apparatus Parameter Comparison for OCT Image Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ophthalmic OCT devices lack effective control mechanisms for image capturing when the current image-capturing region or resolution is inferior to that of previous captures, leading to potential suboptimal or inappropriate post-treatment observations.
Innovation Solution
An ophthalmic apparatus with an acquiring unit for parameters of first and second tomographic images, and a warning unit that compares these parameters to control and issue warnings for image capturing, ensuring appropriate image-capturing settings by determining whether post-treatment observations can be performed based on the comparison between the image-capturing regions and resolutions.

Engineering Contradiction Analysis
1Reliability
If image capturing is performed without comparing parameters with past captures, then the device can be operated simply, but suboptimal or inappropriate post-treatment observations may occur
Solution Approach 1:
The system performs preliminary comparison of image-capturing parameters (such as resolution, field of view, scan density) between current and past captures before executing the actual image acquisition. This preliminary action ensures that the current device capabilities are adequate for post-treatment observation, preventing suboptimal imaging while maintaining operational simplicity through automated parameter verification.
2Productivity
If the current image-capturing region or resolution is inferior to past captures, then capturing can be performed quickly, but the observation quality deteriorates
Solution Approach 1:
The system implements feedback control by comparing current image-capturing parameters (resolution, field of view, scan density) with those of past captures. When the current parameters are found to be inferior, the system provides feedback to prevent capture or alert the operator, ensuring that observation quality is maintained while allowing rapid capture to proceed when parameters are adequate.
3Reliability
If parameter comparison and warning mechanisms are implemented, then inappropriate capturing is prevented, but the operation process becomes more complex
Solution Approach 1:
The system performs self-verification by automatically comparing its own image-capturing parameters with stored reference parameters from past captures. This self-service mechanism ensures that the device independently determines whether current capabilities are sufficient for post-treatment observation, eliminating the need for manual parameter checking by operators while maintaining operational simplicity.
