Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ocular imaging techniques, such as OCT, lack the ability to effectively capture the dynamic effects of movement on ocular tissue, providing limited information on tissue characterization, especially regarding motion.
Innovation Solution
An ocular imaging device incorporating an OCT system with adjustable targets and control circuitry to align the patient's eye at various angular orientations, allowing for imaging of ocular tissue in motion by selectively activating LED lights and controlling the OCT imaging device to capture images at different target locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If OCT imaging is used to capture ocular tissue, then depth penetration and resolution are improved, but the ability to capture dynamic movement effects on tissue is lost
Solution Approach 1:
The system dynamically adjusts the angular orientation of the OCT imaging device to track and capture moving ocular tissue structures. By making the imaging system adaptive to tissue motion rather than static, it simultaneously achieves high-resolution depth penetration and dynamic movement effect capture, resolving the contradiction between measurement precision and motion capture capability.
2Loss of information
If the OCT device is made more complex to capture motion, then motion information is improved, but device complexity increases
Solution Approach 1:
The system uses feedback from detecting ocular tissue motion to automatically adjust the angular orientation of the OCT imaging device. This closed-loop feedback mechanism captures complete motion information while avoiding unnecessary system complexity by using intelligent control rather than mechanically complex multi-device setups.
