Intraocular Image Integration for Wide-Range Surgical Observation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image processing systems for retinal surgical operations are limited in their ability to observe the inside of the eye in a wide range simultaneously, making it difficult to determine the position and direction of surgical instruments, especially when switching between posterior pole and wide-angle observations.
Innovation Solution
An image processing device and system that integrate ophthalmologic images from multiple devices by correlating intraocular positions to generate a single image indicating intraocular information over a wider range than each individual image, allowing for simultaneous observation of a broader area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate images or superimposed images of endoscope posture and intraocular images are presented, then the position and direction of surgical instruments can be determined, but the observation range is limited and cannot provide a wider view of intraocular structures
Solution Approach 1:
The patent merges the endoscope posture image with the intraocular image into a single integrated display. The endoscope posture is represented by a graphical overlay (such as a directional indicator or icon) superimposed on the intraocular image itself, rather than showing them as separate images. This integration allows surgeons to simultaneously see both the intraocular anatomy and the endoscope position/direction within the same visual field, expanding the effective observation range while maintaining precise position determination.
2Loss of information
If multiple ophthalmologic observation devices are used to acquire images, then comprehensive intraocular information can be obtained, but the complexity of image integration and position correlation increases
Solution Approach 1:
The patent introduces an image processing device as an intermediary that automatically performs the complex tasks of image integration and position correlation. This intermediary system receives images from multiple ophthalmologic observation devices, correlates their positions using tracking information, and generates an integrated display automatically. By delegating these complex processing tasks to a dedicated intermediary system, the patent reduces the operational complexity for surgeons while maintaining complete intraocular information from multiple devices.
3Area of stationary object
If wide-angle observation lens is used in surgical microscope, then wider fundus observation is possible, but posterior pole detail observation capability is reduced
Solution Approach 1:
The patent transitions from a single two-dimensional view to a multi-dimensional integrated display that combines wide-angle fundus images with detailed posterior pole images and endoscope posture information. By integrating images from multiple observation devices with different fields of view into a single composite display, the system simultaneously provides both the wide fundus overview and the detailed posterior pole visualization, effectively adding a dimensional layer of information integration that resolves the trade-off between observation range and detail precision.

AI summary
There is provided an image processing device for observing an inside of an eye in a wider range. The image processing device includes an integration processing unit that integrates ophthalmologic images acquired by a plurality of types of ophthalmologic image capturing devices by correlating intraocular positions and generates one integrated image indicating intraocular information in a range wider than a range indicated by each of the ophthalmologic images.
