After you have installed everything, execute this command in this repository root folder:

We are lifting a server to run this viewer because of cornerstoneWADOImageLoader. This package tries to load some of its depedencies using a hard code path that, if we open the index.html file with a browser, we have some load issues because of how the paths will be resolved. Using a server we create a virtual path which will solve this issue.

DICOM Server

This exaple expects a server running on http://localhost:4000 which provides a file named mock.json. This JSON will contain a list of DICOM URLs to be downloaded by this viewer. Example below:

{
  "name": "default case",
  "urls": [
    "http://localhost:4000/1.dcm",
    "http://localhost:4000/2.dcm",
    "http://localhost:4000/3.dcm",
    "http://localhost:4000/4.dcm",
    "http://localhost:4000/5.dcm"
  ]
}

This URL is hard coded at /src/viewer/connector.js on line 2. Please change this line to access the right server.

This viewer expected that each time we request for the mock.json file we have a different set of DICOM files to evaluate.

What is missing?

• The login/logout features are mocked. We have in place a dumb feature to just have the feel of a login being done. Any email and password will suffice for now;
• Submitting measurements is mocked too. This is also another simple code to just mock the feel of submitting the measurements;
• A better way to define which server will provide our DICOMs;
• Tests.
