Google Cloud Healthcare
The Google Cloud Healthcare API is a powerful option for storing medical imaging data in the cloud.
An alternative to deploying your own PACS is to use a software-as-a-service provider such as Google Cloud. The Cloud Healthcare API promises to be a scalable, secure, cost effective image storage solution for those willing to store their data in the cloud. It offers an almost-entirely complete DICOMWeb API which requires tokens generated via the OAuth 2.0 Sign In flow. Images can even be transcoded on the fly if this is desired.
Setup a Google Cloud Healthcare Project​
Create a Google Cloud account
Create a project in Google Cloud
Enable the Cloud Healthcare API for your project.
- (Optional): Create a Dataset and Data Store for storing your DICOM data
Enable the Cloud Resource Manager API for your project.
- Note: If you are having trouble finding the APIs, use the search box at the top of the Cloud console.
Go to APIs & Services > Credentials to create an OAuth Consent screen and fill in your application details.
- Under Scopes for Google APIs, click "manually paste scopes".
- Add the following scopes:
https://www.googleapis.com/auth/cloudplatformprojects.readonly
https://www.googleapis.com/auth/cloud-healthcare
Go to APIs & Services > Credentials to create a new set of credentials:
- Choose the "Web Application" type
- Set up an OAuth 2.0 Client ID
- Add your domain (e.g.
http://localhost:3000
) to Authorized JavaScript origins. - Add your domain, plus
callback
(e.g.http://localhost:3000/callback
) to Authorized Redirect URIs. - Save your Client ID for later.
(Optional): Enable Public Datasets that are being hosted by Google: https://cloud.google.com/healthcare/docs/resources/public-datasets/
Run the viewer with your OAuth Client ID​
- Open the
config/google.js
file and changeYOURCLIENTID
to your Client ID value. - Run the OHIF Viewer using the config/google.js configuration file
cd OHIFViewer
yarn install
APP_CONFIG=config/google.js yarn run dev
Running via Docker​
The OHIF Viewer Docker container can be connected to Google Cloud Healthcare by providing a Client ID at runtime. This is a very simple method to get up and running.
- Install Docker (https://www.docker.com/)
- Run the Docker container, providing a Client ID as an environment variable.
Client IDs look like
xyz.apps.googleusercontent.com
.
docker run --env CLIENT_ID=$CLIENT_ID --publish 5000:80 ohif/viewer:latest
