Ophthalmic Image Display Synchronization for Cross-Section Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ophthalmic diagnostic imaging techniques face difficulties in smoothly and promptly observing multiple images, such as B mode and blood vessel enhanced images, while switching between different cross-sections and parameter settings, making it challenging to compare and display images effectively.
Innovation Solution
An ophthalmic image display device with a display controller that synchronously updates the display of B mode and blood vessel enhanced images based on the movement of a cross-section position indicator, allowing for real-time adjustment and display of multiple images with similar parameter settings in a predetermined layout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional techniques are used to display multiple images sequentially, then the device complexity is low, but the productivity and ease of operation deteriorate due to inability to smoothly compare images before and after switching
Solution Approach 1:
The patent transitions from sequential one-dimensional image display to parallel multi-dimensional display by showing multiple images (B mode, blood vessel enhanced, and front images) simultaneously on the display means. This allows doctors to compare images across different dimensions (different cross-sections, different parameter settings) without switching, directly improving diagnostic speed while the synchronization mechanism manages complexity.
Solution Approach 2:
The display controller is designed to universally handle multiple image types (B mode images, blood vessel enhanced images, front images) and automatically synchronize their cross-section positions. This multi-functional capability allows a single system to manage diverse image formats and parameters, improving productivity without proportionally increasing device complexity.
2Ease of operation
If conventional techniques are used to switch between different image displays, then the operation procedure is simple, but the ease of operation worsens due to inability to re-display previous images and troublesome work of confirming setting contents
Solution Approach 1:
The system provides automatic feedback by displaying cross-section position indicators on front images that show the correspondence between different image types. When a doctor selects a cross-section position, the system automatically adjusts and displays all related images at their corresponding positions, eliminating the need for manual setting confirmation and reducing the time loss associated with switching between images.
Solution Approach 2:
The display controller performs preliminary synchronization of cross-section positions for multiple images before the doctor needs to compare them. By pre-establishing the correct positioning and correspondence of images across different modes and parameter settings, the system eliminates the need for time-consuming manual adjustment and setting confirmation during the diagnostic process.
3Productivity
If conventional techniques are used to display images with different parameter settings, then the device complexity is low, but the productivity deteriorates due to inability to display in parallel images with similar parameter settings
Solution Approach 1:
The system implements dynamic synchronization where the display controller continuously monitors and adjusts the cross-section positions of multiple images in real-time based on user interactions. This dynamic adaptation allows the system to efficiently handle various image types and parameter settings without requiring complex manual configuration, thereby improving diagnostic efficiency while managing control complexity through automated responsive behavior.

AI summary
An ophthalmic image display device having, a display controller that displays a B mode image, a blood vessel enhanced image representing a same cross section as the B mode image, and one or more front images individually formed based on a three dimensional data set acquired by performing optical coherence tomography on a subject's eye in a predetermined layout. Further, the display controller displays a cross section position indicator that indicates a position of a cross section of the B mode image over at least one of the one or more front images. In addition, the display controller synchronously performs changing of a display position of the cross section position indicator and updating of a display of each of the B mode image and the blood vessel enhanced image in accordance with an operation for moving the cross section position indicator performed using an operation unit.
