Introduction
The Open Health Imaging Foundation (OHIF) Viewer is an open source, web-based, medical imaging viewer. It can be configured to connect to Image Archives that support DicomWeb, and offers support for mapping to proprietary API formats. OHIF maintained extensions add support for viewing, annotating, and reporting on DICOM images in 2D (slices) and 3D (volumes).
The Open Health Imaging Foundation intends to provide a simple general purpose DICOM Viewer which can be easily extended for specific uses. If you find yourself unable to extend the viewer for your purposes, please reach out via our GitHub issues. We are actively seeking feedback on ways to improve our integration and extension points.

Getting Started
Setup
Fork & Clone
If you intend to contribute back changes, or if you would like to pull updates we make to the OHIF Viewer, then follow these steps:
- Fork the OHIF/Viewers repository
- Create a local clone of your fork
git clone https://github.com/YOUR-USERNAME/Viewers
- Add OHIF/Viewers as a remote repository labled
upstream- Navigate to the cloned project's directory
git remote add upstream https://github.com/OHIF/Viewers.git
With this setup, you can now sync your fork to keep it up-to-date with the upstream (original) repository. This is called a "Triangular Workflow" and is common for Open Source projects. The GitHub blog has a good graphic that illustrates this setup.
Private
Alternatively, if you intend to use the OHIF Viewer as a starting point, and you aren't as concerned with syncing updates, then follow these steps:
- Navigate to the OHIF/Viewers repository
- Click
Clone or download, and thenDownload ZIP - Use the contents of the
.zipfile as a starting point for your viewer
NOTE: It is still possible to sync changes using this approach. However, submitting pull requests for fixes and features are best done with the separate, forked repository setup described in "Fork & Clone"
Developing
Requirements
- Node.js & NPM
- Yarn
- Yarn workspaces should be enabled:
yarn config set workspaces-experimental true
Kick the tires
Navigate to the root of the project's directory in your terminal and run the following commands:
# Restore dependencies yarn install # Start local development server yarn run dev You should see the following output:
@ohif/viewer: i ｢wds｣: Project is running at http://localhost:3000/
@ohif/viewer: i ｢wds｣: webpack output is served from /
@ohif/viewer: i ｢wds｣: Content not from webpack is served from D:\code\ohif\Viewers\platform\viewer
@ohif/viewer: i ｢wds｣: 404s will fallback to /index.html
# And a list of all generated files 🎉 Celebrate 🎉

# Build static assets to host a PWA yarn run build # Build packaged output (script-tag use) yarn run build:package Troubleshooting
- If you receive a "No Studies Found" message and do not see your studies, try changing the Study Date filters to a wider range.
- If you see a 'Loading' message which never resolves, check your browser JavaScript console inside the Developer Tools to identify any errors.
OHIF Medical Imaging Viewer
The OHIF Viewer is a zero-footprint medical image viewer provided by the Open Health Imaging Foundation (OHIF). It is a configurable and extensible progressive web application with out-of-the-box support for image archives which support DICOMweb.
About
The OHIF Medical Imaging Viewer is for viewing medical images. It can retrieve and load images from most sources and formats; render sets in 2D, 3D, and reconstructed representations; allows for the manipulation, annotation, and serialization of observations; supports internationalization, OpenID Connect, offline use, hotkeys, and many more features.
Almost everything offers some degree of customization and configuration. If it doesn't support something you need, we accept pull requests and have an ever improving Extension System.
Why Choose Us
Community & Experience
The OHIF Viewer is a collaborative effort that has served as the basis for many active, production, and FDA Cleared medical imaging viewers. It benefits from our extensive community's collective experience, and from the sponsored contributions of individuals, research groups, and commercial organizations.
Built to Adapt
After more than 5-years of integrating with many companies and organizations, The OHIF Viewer has been rebuilt from the ground up to better address the varying workflow and configuration needs of its many users. All of the Viewer's core features are built using it's own extension system. The same extensibility that allows us to offer:
- 2D and 3D medical image viewing
- Multiplanar Reconstruction (MPR)
- Maximum Intensity Project (MIP)
- Whole slide microscopy viewing
- PDF and Dicom Structured Report rendering
- User Access Control (UAC)
- Context specific toolbar and side panel content
- and many others
Can be leveraged by you to customize the viewer for your workflow, and to add any new functionality you may need (and wish to maintain privately without forking).
Support
We offer support through GitHub Issues. You can:

Quick Start Deployment
This is only one of many ways to configure and deploy the OHIF Viewer. To learn more about your options, and how to choose the best one for your requirements, check out our deployment recipes and documentation.
The fastest and easiest way to get started is to include the OHIF Viewer with a script tag. In practice, this is as simple as:
- Including the following dependencies with script tags:
- Have an element with an ID of
rooton the page - Configure the OHIF Viewer at
window.config:
window.config = { routerBasename: '/', servers: { dicomWeb: [ { name: 'DCM4CHEE', qidoRoot: 'https://server.dcmjs.org/dcm4chee-arc/aets/DCM4CHEE/rs', wadoRoot: 'https://server.dcmjs.org/dcm4chee-arc/aets/DCM4CHEE/rs', qidoSupportsIncludeField: true, imageRendering: 'wadors', thumbnailRendering: 'wadors', }, ], }, };
- Install the viewer:
window.OHIFViewer.installViewer(window.config);
This exact setup is demonstrated in this CodeSandbox and in our Embedding The Viewer deployment recipe.
