Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image guidance systems in ophthalmic surgery require manual initialization by surgeons, which adds time, distracts from the procedure, and necessitates additional equipment and space in the operating room.
Innovation Solution
An ophthalmic system that automatically initializes image-guided surgery by detecting a patient's eye in the intra-operative scene and performing image registration without user input, generating overlay content for real-time surgical guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual initialization is used in conventional image guidance systems, then surgeons can control the initialization process, but this adds time, distracts from the procedure, and necessitates additional equipment and space
Solution Approach 1:
The system performs self-initialization by automatically detecting the eye in the surgical scene and executing image registration without requiring surgeon intervention. The processor monitors images from the imaging device, detects eye features, and initializes the image-guided surgery autonomously, eliminating the need for manual control while reducing initialization time
Solution Approach 2:
The patent replaces the manual mechanical initialization process with an automated computer vision system. The processor uses image processing algorithms to detect eye features and perform registration, substituting the surgeon's manual actions with an automated digital system that reduces time and distraction
2Ease of operation
If manual initialization is used in conventional image guidance systems, then surgeons can control the initialization process, but this necessitates additional equipment and space in the operating room
Solution Approach 1:
The system merges the initialization functionality into the existing image guidance system. The processor that already processes surgical images is extended to perform eye detection and automatic initialization, eliminating the need for separate manual control equipment and reducing overall system complexity
Solution Approach 2:
The imaging device and processor are designed to serve multiple functions: capturing surgical scenes, detecting eye features, and performing image registration. This multi-functionality eliminates the need for dedicated manual initialization equipment, reducing device complexity and space requirements
3Productivity
If automatic initialization is implemented, then manual interactions are reduced and time is saved, but the system must accurately detect and register images without user input
Solution Approach 1:
The system uses feedback from image analysis to guide the initialization process. The processor continuously monitors images from the imaging device, analyzes eye features, and adjusts registration parameters based on detected features, ensuring accurate automatic initialization while maintaining high speed
Solution Approach 2:
The system performs preliminary eye detection and feature extraction before finalizing the registration. By pre-processing images to identify key eye features and prepare registration data in advance, the system ensures both speed and accuracy in the automatic initialization process
Data Source
AI summary
In certain embodiments, an ophthalmic system and computer-implemented method for automatically initializing an image guided surgery are described. The initialization includes monitoring a scene using multiple images captured by a first imaging device. An eye of a user is detected within a first image of the multiple images. In response to detecting the eye of the user, a registration procedure is initiated with the first image and a reference image of the eye of the user to generate a set of transformation information. A set of overlay content is generated based on the set of transformation information. The set of overlay content includes a transformed first image or a transformed reference image. Overlay content is presented onto the scene via a second imaging device.
