Combined Eye Imaging Device Fundus Depth Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current eye examination methods require multiple devices to visualize both the fundus and deeper structures, leading to increased costs, time consumption, and discomfort for patients.
Innovation Solution
A combined examination device incorporating a slit lamp microscope, scanning digital ophthalmoscope (SDO), and optical coherence tomograph (OCT) allows for simultaneous imaging of the fundus and underlying structures using sequential scanning and depth-resolved imaging, enabling stereoscopic visualization without repositioning the patient.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple examination devices are used to examine both fundus and deeper structures, then imaging capability is improved, but examination time and patient discomfort increase
Solution Approach 1:
The patent combines multiple examination devices (SDO for fundus imaging and OCT for deeper structure imaging) into a single integrated examination device. This merging allows both fundus and deeper structures to be examined sequentially without requiring patient repositioning, thereby maintaining comprehensive imaging capability while reducing examination time and patient discomfort.
Solution Approach 2:
The integrated examination device is designed to perform multiple functions: it can execute both SDO examinations for fundus imaging and OCT examinations for deeper structure imaging. This multi-functionality eliminates the need for separate devices and repositioning, resolving the contradiction between comprehensive imaging capability and examination efficiency.
2Adaptability or versatility
If multiple examination devices are used to examine both fundus and deeper structures, then imaging capability is improved, but device cost increases
Solution Approach 1:
The patent integrates multiple examination devices into a single unified system, combining SDO and OCT functionalities. This merging reduces the total number of separate devices required, thereby lowering overall equipment costs while maintaining the ability to perform both fundus and deeper structure imaging.
Solution Approach 2:
The integrated device provides universal functionality for both SDO and OCT examinations, eliminating the need to purchase and maintain separate specialized devices. This multi-functionality reduces device complexity and cost while preserving comprehensive imaging capabilities.
3Adaptability or versatility
If multiple examination devices are used to examine both fundus and deeper structures, then imaging capability is improved, but patient comfort deteriorates
Solution Approach 1:
The patent combines SDO and OCT examination functions into a single device that maintains a fixed position relative to the patient. This integration allows sequential imaging of fundus and deeper structures without requiring patient repositioning, thereby improving patient comfort while maintaining comprehensive imaging capability.
Solution Approach 2:
The integrated examination device provides universal imaging capabilities for both fundus and deeper structures from a single fixed position. This eliminates the need for patient repositioning between devices, significantly improving ease of operation and patient comfort during the examination process.
