Imaging Control Apparatus for OCT Optical Path Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ophthalmic imaging systems, particularly OCT apparatuses, require time-consuming and labor-intensive adjustments when changing imaging positions or modes, leading to increased operator load and prolonged imaging times due to the need for readjustment of optical path lengths and alignment.
Innovation Solution
A control apparatus that selects image-capturing sites and determines necessary adjustments based on pre- and post-change image-capturing conditions, automatically controlling adjustments such as coherence gate positioning and alignment to minimize readjustment time by optimizing the order of image-capturing modes and conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment of optical path length is performed, then adjustment precision can be achieved, but operator load increases and adjustment time is prolonged
Solution Approach 1:
The system automatically detects the required optical path length adjustment based on image-capturing conditions and performs the adjustment without operator intervention. The control unit determines adjustment requirements and executes them autonomously, making the system self-serve its own alignment needs.
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated control system that uses image-capturing condition analysis to determine and execute optical path length adjustments, substituting human operation with an automated decision-making and execution system.
2Measurement precision
If manual adjustment of optical path length is performed, then adjustment precision can be achieved, but adjustment time is prolonged
Solution Approach 1:
The control unit determines the required optical path length adjustment in advance based on the selected image-capturing site and conditions, before actual image capture begins. This preliminary determination eliminates time-consuming trial-and-error adjustments during the imaging process.
Solution Approach 2:
The automated control system replaces manual adjustment operations with algorithm-based determination and automatic execution, significantly reducing the time required to achieve precise optical path length alignment.
3Manufacturing precision
If readjustment is performed when changing image-capturing sites or modes, then imaging quality is maintained, but operator load increases
Solution Approach 1:
When the image-capturing site or mode changes, the control unit automatically determines whether readjustment is needed and executes it without requiring operator intervention. The system monitors condition changes and self-corrects to maintain imaging quality.
Solution Approach 2:
The system continuously monitors image-capturing conditions and automatically triggers readjustment when conditions change, using feedback from the selected site and mode parameters to maintain optimal imaging quality without operator burden.
4Manufacturing precision
If readjustment is performed when changing image-capturing sites or modes, then imaging quality is maintained, but imaging time is prolonged
Solution Approach 1:
The control unit determines readjustment requirements in advance when image-capturing conditions change, before actual imaging resumes. This preliminary determination minimizes downtime and ensures quality is maintained without prolonged delays.
Solution Approach 2:
Automatic control replaces manual readjustment operations, significantly reducing the time required to maintain imaging quality when changing sites or modes, as the system executes adjustments without human intervention delays.
