Draw ROI​

The Clinical Viewer tool provides many different options and ways to annotate an image, allowing template shapes as well as freehand drawing of ROIs. For the purposes of this tutorial, we will stick to only using template shapes as an example.

  2. Choose an Annotation Class of either Neoplasm or Tissue. In this example, we will use Neoplasm.

  3. Choose an Annotation Type. In this example we chose Box.

  4. Check the "Measure" box to enable ROI measuring.

  5. Click the "Select" button to return to the WSI Viewer with the draw tool active.
