Medical Image Viewer Compatibility Detection via Client-Side Feature Inversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical image viewer systems face challenges in accurately determining client compatibility, leading to potential loss of functionality and unexpected results due to 'dead code' execution on the client side and inaccurate server-side compatibility detection.
Innovation Solution
A zero footprint approach is implemented, where client compatibility is determined in the background while a temporary view is displayed, allowing for dynamic rendering and presentation modifications based on detected capabilities, such as WebGL and WebSocket support, to ensure seamless image data transfer and rendering.

Engineering Contradiction Analysis
1Measurement precision
If server-side compatibility detection is used, then compatibility can be determined before image display, but it leads to inaccurate detection and dead code execution on the client side
Solution Approach 1:
The patent inverts the traditional server-side compatibility detection approach by implementing client-side detection. Instead of the server determining compatibility and sending appropriate code, the client browser actively detects its own compatibility features (WebGL, WebSocket, Canvas) and reports back to the server. This inversion ensures accurate detection because the client directly assesses its own capabilities without server guessing, eliminating dead code execution while maintaining functionality consistency.
Solution Approach 2:
The client browser performs self-service compatibility detection by autonomously checking for supported features like WebGL, WebSocket, and Canvas capabilities. The browser independently determines its own compatibility level and communicates this information to the server, eliminating the need for server-side compatibility determination logic. This self-service approach ensures accurate detection since the client is the best judge of its own capabilities.
2Productivity
If client compatibility is determined in the background during temporary view display, then seamless image data transfer is enabled, but it requires additional client-side processing
Solution Approach 1:
The patent implements preliminary action by performing compatibility detection in the background during the display of a temporary view (splash screen) before the actual medical image data is transferred and rendered. The client browser checks for supported features and establishes communication channels ahead of time, so that when the real image data arrives, the system is already optimized for efficient transfer and rendering without requiring additional processing steps.
Solution Approach 2:
The compatibility detection process runs continuously in the background without interrupting the user experience. The temporary view is displayed continuously while compatibility checks proceed, and once compatibility is established, the transition to full image display is seamless. This continuous action ensures productivity improvement without adding perceived complexity to the user interaction.
3Reliability
If dynamic rendering modifications are applied based on client capabilities, then functionality consistency is achieved, but it requires complex compatibility detection mechanisms
Solution Approach 1:
The patent applies parameter changes by dynamically modifying rendering parameters and presentation settings based on the client's detected capabilities. Instead of creating entirely different code paths for different browsers, the system changes specific rendering parameters (such as using WebGL vs. Canvas, enabling or disabling certain features) based on the compatibility information received from the client. This approach achieves functionality consistency while keeping the detection mechanism relatively simple.
Data Source
AI summary
Certain examples provide systems and methods to determine client compatibility. An example method includes receiving a request at an image viewer from a client browser for display of medical image data. The example method includes providing a temporary view to the client browser in response to the request. The example method includes determining client compatibility with the viewer and an associated server in the background at a client device executing the client browser while the temporary view is displayed at the client browser. The example method includes requesting the image data from the server based on the client compatibility determination. The example method includes rendering the image data and providing to the client browser based on the client compatibility determination, the rendering and presentation of the image data modified to enable or disable capability of at least one of the viewer and the server based on the client compatibility determination.
