Preview The OHIF Viewer

ATTENTION! You are looking at the docs for the OHIF-v3 Viewer (third time is always a charm). If you're looking for the our OHIF-v2 (React stable version) or OHIF-v1 (deprecated Meteor version) select it's version from the dropdown box in the top left corner of this page.

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).

 

What's new in OHIF-v3

OHIF-v3 is our second try for a React-based viewer, and is the third version of our medical image web viewers from the start. The summary of changes include:

• Addition of workflow modes

  • Often, medical imaging use cases involves lots of specific workflows that re-use functionalities. We have added the capability of workflow modes, that enable people to customize user interface and configure application for specific workflow.
  • The idea is to re-use the functionalities that extensions provide and create a workflow. Brain segmentation workflow is different from prostate segmentation in UI for sure; however, they share the segmentation tools that can be re-used.
  • Our vision is that technical people focus of developing extensions which provides core functionalities, and experts to build modes by picking the appropriate functionalities from each extension.

• Redux store has been removed from the viewer, and a cleaner, more powerful

• tailwind CSS

• End-to-end test suite

Where to next?

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.
