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.

The OHIF Viewer 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.
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.
After more than 8-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
- Segmentation rendering as labelmaps and contours
- 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).

master
- The latest dev release
This is typically where the latest development happens. Code that is in the master branch has passed code reviews and automated tests, but it may not be deemed ready for production. This branch usually contains the most recent changes and features being worked on by the development team. It's often the starting point for creating feature branches (where new features are developed) and hotfix branches (for urgent fixes).
Each package is tagged with beta version numbers, and published to npm such as @ohif/ui@3.6.0-beta.1
Once the master
branch code reaches a stable, release-ready state, we conduct a comprehensive code review and QA testing. Upon approval, we create a new release branch from master
. These branches represent the latest stable version considered ready for production.
For example, release/3.5
is the branch for version 3.5.0, and release/3.6
is for version 3.6.0. After each release, we wait a few days to ensure no critical bugs. If any are found, we fix them in the release branch and create a new release with a minor version bump, e.g., 3.5.1 in the release/3.5
branch.
Each package is tagged with version numbers and published to npm, such as @ohif/ui@3.5.0
. Note that master
is always ahead of the release
branch. We publish docker builds for both beta and stable releases.
Here is a schematic representation of our development workflow:
- Yarn 1.17.3+
- Node 18+
- Yarn Workspaces should be enabled on your machine:
yarn config set workspaces-experimental true
- Fork this repository
-
Clone your forked repository
git clone https://github.com/YOUR-USERNAME/Viewers.git
- Navigate to the cloned project's directory
- Add this repo as a
remote
namedupstream
git remote add upstream https://github.com/OHIF/Viewers.git
-
yarn install
to restore dependencies and link projects
From this repository's root directory:
# Enable Yarn Workspaces
yarn config set workspaces-experimental true
# Restore dependencies
yarn install
These commands are available from the root directory. Each project directory
also supports a number of commands that can be found in their respective
README.md
and package.json
files.
