Getting Started

Getting the Code

Either clone the repository using Git:

git clone git@github.com:OHIF/Viewers.git

or Download the latest Master as a ZIP File.

Run the OHIF Viewer application against our public DICOM server

You can either spin up locally or run with Docker.

running locally

1. Install Node.js
2. Open a new terminal tab, go under ohif-viewer directory and install all dependency packages via yarn

yarn install

3. Run the application

yarn start

Note: This will connect to our public DICOMWeb server so you can verify your installation. Follow the next section to connect to your own local or remote DICOMWeb server.

4. Launch the OHIF Viewer Study List. By default the address is http://localhost:3000/. The port may vary so check the start up output messages such as:

Compiled successfully!

You can now view ohif-viewer in the browser.

  Local:            http://localhost:5000/
  On Your Network:  http://10.74.20.83:5000/

Note that the development build is not optimized.
To create a production build, use yarn build.

If everything is working correctly, you should see the studies from our public archive when you visit the Study List.

5. Double-click on a Study in the Study List to launch it in the Viewer

   If everything is working correctly, you should see your study load into the Viewer.

Set up a local DICOM server

1. Choose and install an Image Archive
2. Upload some data into your archive (e.g. with DCMTK's storescu or your archive's web interface)
3. Keep the server running

Open Source DICOM Image Archive Options

Archive	Installation
DCM4CHEE Archive 5.x	Installation with Docker
Orthanc	Installation with Docker
DICOMcloud (DICOM Web only)	Installation
OsiriX (Mac OSX only)
Horos (Mac OSX only)

Feel free to make a Pull Request if you want to add to this list.

Orthanc with Docker

Depending on whether or not you want uploaded studies to persist in Orthanc after Docker has been closed, there are two different methods for starting the Docker image:

Temporary data storage

This command will start an instance of the jodogne/orthanc-plugins Docker image. All data will be removed when the instance is stopped!

docker run --rm -p 4242:4242 -p 8042:8042 jodogne/orthanc-plugins

Persistent data storage

In order to allow your data to persist after the instance is stopped, you first need to create an image and attached data volume with Docker. The steps are as follows:

1. Create a persistent data volume for Orthanc to use

   docker create --name sampledata -v /sampledata jodogne/orthanc-plugins
   

   Note: On Windows, you need to use an absolute path for the data volume, like so:

   docker create --name sampledata -v '//C/Users/erik/sampledata' jodogne/orthanc-plugins
   

2. Run Orthanc from Docker with the data volume attached

   docker run --volumes-from sampledata -p 4242:4242 -p 8042:8042 jodogne/orthanc-plugins
   

3. Upload your data and it will be persisted

Setting up OHIF Viewer with Orthanc as an example

Once you have Orthanc running with docker either with temporary data storage or persistent data storage we con move forward with the next steps.

1. Load orthanc with a dataset you might want to use. To upload data use http://localhost:8042/app/explorer.html.

   orthanc is the username and password for orthanc docker

2. Go under http://localhost:8042/app/explorer.html#upload and upload your DICOM files there

3. After you load the data, open a new terminal tab in the ohif-viewer directory and install all dependency packages via Yarn

yarn install

3. Run the application using one of the available configuration files. the following command assumes you are under the root folder

export REACT_APP_CONFIG=$(cat ./config/local_orthanc.js)
yarn start

This uses the Custom Environment Variables of Create-React-App to pass in your configuration. The example above will not work on Windows. Please visit the link to read about how to set environment variables on Windows.

4. Launch the OHIF Viewer Study List by visiting http://localhost:3000/ in a web browser.

   If everything is working correctly, you should see the Study List from your archive when you visit the Study List.

5. Double-click on a Study in the Study List to launch it in the Viewer

   If everything is working correctly, you should see your study load into the Viewer.

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.
• If you receive exit code 137, increase the amount of memory available to your docker instances.
• If you see any errors in your server console, check the Troubleshooting page for more in depth advice.
