Medical Web Viewer Introduction

Summary

The LEADTOOLS Medical Web Viewer Framework enables programmers to quickly build high-quality, full-featured, web-based medical image viewer applications.

It includes WCF components, HTML5 / JavaScript controls and services that enable you to implement high-level interfaces for distributing medical studies from a server to web clients, even with very limited knowledge of web hosting and web service development. This is ideal for web-based solutions like querying patient studies and viewing images from remote computers and mobile devices, including smartphones and tablets.

The plug-in capable design also allows developers to use the framework for non-DICOM images or binary data transfer, and to extend an implemented web service to include application-specific data transfer and communication capabilities.

The LEADTOOLS Medical Web Viewer Framework Module architecture includes both server-side and client-side components with security options. The framework provides components for developing rich client (2D / 3D) applications that target Windows Internet Explorer and components for developing zero-footprint, cross-platform client applications that target any browser and platform supporting HTML5.

Key Features

Zero-Footprint, Cross-Platform HTML 5 Viewer:
- Based on HTML5 / Javascript: targets any browser / platform that supports HTML5
- Support for 2D image display
- Tools most commonly used in radiology applications, like window-level, rotate and flip
- Scrolling, zooming, and panning
- Image markup and annotation
- Measurement tools
- Low-memory usage is always considered, image data is streamed on demand
- Signed and unsigned display for extended grayscale images typical of medical applications
- Series Stacking
- Multiple display layouts, including stack, cine and series view
- Synchronized scrolling, zooming, and panning
Web Services:
- Addresses and interfaces to manage, store, query and retrieve DICOM data sets, image sets or thumbnails
- Query for patient, study and series
- Get DICOM tags only
- Get complete DICOM files with all image information
- Get full resolution image or a thumbnail representation
Dynamically remove or add plug-in services as needed:
- Can be configured with any type of security supported by WCF, including certificates
- Limit service access to authenticated users
- Options to manage user authentication and authorization
- Permissions provide authorization for accessible resources for authenticated users
Browser Cache: Take advantage of the built-in browser cache
Multi-Resolution and Tiled Image (MRTI) Support For Very Large Images:
- Take advantage of built-in MRTI support
- Display images up to 1 TB over the web using the least bandwidth possible
- Save memory resources displaying large images by only loading those portions displayed in the viewer
- Implement dynamic user interfaces that load the image as the user pans, scrolls, and zooms
- Transfer only the resolutions and tiles requested by the viewer
- Cache requested tiles on the server for future reuse
