Adaptive Overlay Image Parameter Adjustment in Surgical Microscopes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During vitreoretinal surgery, the overlay images from optical scanners often have different image quality parameters than the surgical microscope images, making it difficult for surgeons to view details due to differences in brightness, contrast, and color palette, which can reduce the ability to see certain details and is cumbersome to adjust independently.
Innovation Solution
An adaptive method and system that adjusts overlay image parameters to match those of the optical image generated by the surgical microscope, including brightness, contrast, and color scale, to improve image quality and viewability without requiring user input, by scanning the optical image to generate corresponding parameters and applying them to the overlay image.

Engineering Contradiction Analysis
1Illumination intensity
If overlay image parameters are adjusted independently to match optical image quality, then image viewability improves, but device complexity and manual adjustment burden increase
Solution Approach 1:
The system automatically adjusts overlay image parameters by extracting parameters from the optical image and applying them to the overlay image without requiring manual user input. The processor autonomously performs parameter extraction, matching, and adjustment to achieve consistent image quality across different image sources.
Solution Approach 2:
The system changes the parameters of the overlay image (brightness, contrast, color scale) to match the parameters extracted from the optical image. This parameter matching ensures that both images have consistent visual characteristics for optimal surgical viewing.
2Stability of the object's composition
If multiple image parameters are adjusted manually to achieve matching quality, then image consistency improves, but time consumption and operational efficiency decrease
Solution Approach 1:
The processor automatically performs parameter extraction from the optical image and applies these parameters to the overlay image without requiring manual user input. This automated process maintains image consistency while eliminating the time-consuming manual adjustment process.
Solution Approach 2:
The system extracts parameters from the optical image in advance and uses them to pre-adjust the overlay image parameters before display. This preliminary parameter matching ensures consistent image quality is achieved automatically without delaying the surgical procedure.
3Device complexity
If overlay image parameters are not adjusted, then device simplicity is maintained, but image quality and surgical precision deteriorate
Solution Approach 1:
The system maintains simplicity by using an automated processor-based approach that extracts parameters from the optical image and applies them to the overlay image without requiring complex manual controls or additional adjustment mechanisms. The automation preserves system simplicity while achieving precise parameter matching.
Solution Approach 2:
The system automatically changes the overlay image parameters to match the optical image parameters, ensuring consistent image quality and surgical precision without requiring complex manual intervention or additional hardware complexity.

AI summary
Image parameters of an overlay image may be adjusted based on image parameters of an optical image displayed in a surgical microscope. The overlay image may then be displayed with the optical image to a user of the surgical microscope.
