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 Rich Client Web Viewer
Based on HTML5 / Javascript: targets any browser / platform that supports HTML5 Based on WinForms: targets Internet Explorer for Windows
Support for 2D image display Support for 2D and 3D imaging display
Tools most commonly used in radiology applications, like window-level, rotate and flip Tools most commonly used in radiology applications, like window-level, rotate, flip, and invert
Scrolling, zooming, and panning Scrolling, zooming, and panning
Image markup and annotation Image markup and annotation
Measurement tools Measurement tools
Region processing tools
Low-memory usage is always considered, image data is streamed on demand Options for low-memory usage in large-study viewing
Signed and unsigned display for extended grayscale images typical of medical applications Signed and unsigned display for extended grayscale images typical of medical applications
Series Stacking Series stacking
Multiple display layouts, including stack, cine and series view
Synchronized scrolling, zooming, and panning
Printing to Windows printers
A light-weight, HTML-based viewer is provided for fast series image viewing. This viewer can be used on any browser or mobile device including iPhone, iPad, Android, and Windows Phone.

WCF Security
Take advantage of the built-in browser cache Client-side Cache Management
  • Client-side caching of download studies for fast reloads and network traffic reduction
  • Local cache storage management
  • Encryption option for local cache to protect patient's health record
CAB File Generator - This wizard generates the .NET runtime rights .CAB file

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
