About

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.

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 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).

Developing

Branches

`master` branch - The latest dev (beta) release

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

`release/*` branches - The latest stable releases

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.
