DICOM_viewer

A Unity hololens viewer for DICOM images

Setup

1. Create a zip file containing your DICOM media directories
2. Deploy the application to the device once
3. Connect the device via usb, and navigate to http://localhost:10080/FileExplorer.htm - USB will give better/more reliable data transfer
4. Navigate to LocalAppData\DICOM_viewer\LocalState
5. Click the Choose File button, and select your zip file. Do not click Upload - at the time of writing, there is a bug in the file explorer (see https://stackoverflow.com/questions/46409655/transfer-file-to-hololens-via-post-httprequest-error-429/47086736#47086736) - instead, enter this code in the javascript console (F12) -

(function(jQuery) {
var pathLinkData = jQuery(".pathLink:last-child").data(),
    path = pathLinkData.path,
    packagename = pathLinkData.packagename,
    knownfolderid = pathLinkData.knownfolderid,
    url = '/api/filesystem/apps/file?knownfolderid=' + knownfolderid + '&packagefullname=' + packagename + '&path=%5C%5C' + path,
    file_data = jQuery('#fileToUpload')[0].files[0],
    form_data = new FormData();

  form_data.append('file', file_data, file_data.name);

  jQuery.ajax({
    url: url,
    dataType: 'text',
    cache: false,
    contentType: false,
    processData: false,
    data: form_data,
    type: 'POST',
    error: function(xhr, textStatus, error) { console.error(error) },

  xhr: function() {
    var xhr = new window.XMLHttpRequest();

    xhr.upload.addEventListener("progress", function(evt) {
      if (evt.lengthComputable) {
        var percentComplete = evt.loaded / evt.total;
        percentComplete = parseInt(percentComplete * 100);
        console.log(percentComplete + "% done");
      }
    }, false);

    return xhr;
  },
    success: function(res){
      alert('uploaded');
      console.log(res);
    }
  });
})(jQuery);

• this is mostly based on doublerebel's stack overflow snippet, I just added a progress indicator

6. Also upload a pin.txt containing your desired PIN via the same method
7. Run the application and it will unzip your zip file

Troubleshooting

If you have issues building to the device (dll version conflicts) - in the built VS project, open Tools->NuGet Package Manager->Manage NuGet Packages For Solution and update Microsoft.NETCore.UniversalWindowsPlatform
