This repository contains a proof-of-concept whole slide imaging viewer powered by a DICOMweb server. This particular tool uses the Google Cloud Healthcare API DICOMweb implementation.

NOTE: This viewer is only for whole slide (i.e. pathology) images. For radiology viewers that work with the Healthcare API check out Weasis (https://github.com/GoogleCloudPlatform/weasis-chcapi-extension), OHIF (https://docs.ohif.org/connecting-to-image-archives/google-cloud-healthcare.html), eUnity (https://demo.eunity.app) or IMS (https://cloudview.imstsvc.com/GoogleDemoViewer/Hub)

You need to have access to the Google Cloud Healthcare API and have created a DICOM store with some DICOM WSIs in it.

Once you have access to the Cloud Healthcare API you can follow the quickstart to create a DICOM store and upload some sample DICOM images.

To create DICOM WSIs you first need to get some pathology images (https://openslide.org/) has some test data you can use) and the convert them to DICOM. To convert to DICOM you can use a tool like the DICOMizer CLI from the Orthanc WSI Plugin.

Once you've created a DICOM store with some DICOM WSIs in it, the following steps will bring up the viewer:

1. Clone this repository
2. Insert client secret id:
   • Open Google Cloud Console
   • Create new OAuth Client ID (type 'Web application')
   • When setting up the OAuth consent screen make sure to add https://www.googleapis.com/auth/cloud-healthcare to the list of scopes.
   • Add http://localhost:8000 to the Authorized JavaScript Origins & Authorized redirect URIs
   • Copy the Client ID into viewer.js
3. Run python -m SimpleHTTPServer 8000 from the root folder of the directory
4. Navigate to http://localhost:8000
