OHIF AWS HealthImaging adapter

Note - The official name for the service is "AWS HealthImaging". Before GA it was called "Amazon HealthLake Imaging" and several references in the code and documentation still reference this old name. These references will be updated shortly

Setting up

Prerequisites

• Node.js +18
• Yarn 1.22.22. Note that OHIF uses a legacy version of yarn, you need to force yarn to use classic mode to build properly.

  > npm i -g yarn # install yarn
  > yarn set version classic # force yarn to use classic version.  Make sure you do this from your repo directories

• OHIF follow the Getting started guide if needed.
• Checkout the latest release branch. 3.8 is known to work, master may be unstable so don't start there in case it is broken

  > git remote add upstream git@github.com:OHIF/Viewers.git # make sure your fork upstream is set properly
  > git fetch upstream # get the list of branches from upstream repo
  > git checkout release/3.8 # switch to a specific branch

• Install ohif-aws-healthimaging package:
• Create an access key in the AWS portal
• Follow AWS documentation on how to create an AWS Health Imaging Datastore and load it with DICOM data
• Start the proxy to secure your access keys

# AWS_HOST
docker run -p 8089:8089 -e AWS_ACCESS_KEY_ID='YOUR_KEY' -e AWS_SECRET_ACCESS_KEY='YOUR_SECRET' -e AWS_REGION='YOUR_REGION' flexview/ohif-aws-healthimaging-proxy

• Add healthimaging as a dependency

yarn cli add-extension ohif-aws-healthimaging

• Add healthimaging adapter as an OHIF plugin platform/viewer/pluginConfig.json

  "extensions": [
    //....
    {
      "packageName": "ohif-aws-healthimaging"
    }
  ],

• Configure the data source to access healthimaging via the proxy

platform/app/public/config/default.js

  //...
  dataSources: [{
    friendlyName: 'AWS HealthImaging',
    namespace: 'ohif-aws-healthimaging.dataSourcesModule.healthlake',
    sourceName: 'healthlake',
    configuration: {
      name: 'healthlake',
      healthlake: {
        datastoreID: $YOUR_DATASTORE_ID,
        endpoint: 'http://localhost:8089',// Add here the address to you proxy
      },
      singlepart: 'bulkdata,video,pdf,image/jphc',
    }
  }
  ],

• Run OHIF

yarn start # in the OHIF platform/viewer folder

• Opening your first exam

http://localhost:3000/viewers?StudyInstanceUIDs=$DICOMStudyUIDHere&ImageSetID=$ImageSetIDHere

FAQ

Why do we need the proxy server?

• You should never expose your AWS keys to the client. We created this tiny proxy with the only purpose of hiding the AWS keys in the backend.
• The Proxy server available here is meant to be for development only. In actual use cases, we encourage you to implement authentication on top of the proxy so you secure access to your data.
