  • HTML5 Zero-footprint Viewer for DICOM and PACS

    The demand for zero-footprint applications is growing rapidly, especially in the health care industry with the increasing popularity and usage of tablets and mobile devices by health care providers. There are many ways to display DICOM images and communicate with a PACS over the web or intranet in a zero-footprint manner, but not all applications are created equal. Any zero-footprint application must do a significant portion of work at the server, but this typically causes a tradeoff in features and performance for which developers must find the proper balance. LEADTOOLS overcomes these problems with an advanced AngularJS framework that is able to query any PACS and window level and annotate 16-bit grayscale images on an HTML5 canvas.

Demo Applications that Include HTML5/JavaScript Zero-footprint DICOM Viewer

HTML5/JavaScript Medical Web Viewer Framework

A zero-footprint Medical viewer with light and dark themes to display DICOM images (pixel data) with window level, density removal, offset, scale, zoom, stack, annotation/markup, and multi-touch support for phone, tablet, and desktop.

It demonstrates zero-footprint 3D volume rendering of multiple volume types including VRT, MIP, MPR, and SSD in the Medical Web Viewer. The viewer does not require browser plugins, desktop utilities, or remote desktop clients and features low resolution and caching options for faster rendering and loading.

DICOM Hanging Protocol Overview - LEADTOOLS Web Viewer

DICOM Hanging Protocol is a new feature in LEADTOOLS Version 19 that helps doctors and radiologists save time when viewing studies.

Before digital imaging, Doctors hung film sheets on an illuminator, or light box. Typically, the sheets were printed and hung in specific locations and orders, thus the name “Hanging Protocol." This can be difficult to reproduce digitally, but the DICOM standards define ways of matching and displaying a patient’s images that doctors can configure, reuse, and share.

3D Cursor - LEADTOOLS Medical Web Viewer

In this video, we will demonstrate the 3D cursor feature found in the LEADTOOLS HTML5, Zero-footprint Medical Viewer. The 3d cursor, also called a 3d localizer, can be used on a study with multiple series captured on different planes and scroll each series so that each image intersects on the voxel represented by the mouse click.

Synchronized Stacking - LEADTOOLS Medical Web Viewer

In this video, we will demonstrate the Series Synchronization feature found in the LEADTOOLS HTML5, Zero-footprint Medical Viewer. When multiple series on the same plane are loaded into the viewer, Series Synchronization will keep the image slices in each viewer cell in line with each other based on their 3-dimensional location information.

LEADTOOLS HTML5/JavaScript Medical Viewer Speedup in April Update

In the recent April 2016 LEADTOOLS Version 19 free update, we significantly improved the speed of loading a series in the HTML5/JavaScript, Zero Footprint Medical Viewer. Watch this side-by-side comparison to see just how much faster it is!
