Medical Web Viewer Introduction


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
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
