Creating overlays

Colored overlays are used to explain findings directly in the image. Here we show how these can be created and what types are available.

Open your case in edit mode before you start

Search for the case you want to edit in the “Cases” tab
Open the case you want to edit by clicking on it
If you havent created a case yet check out the section about uploading images and case creation
Once you have opened the desired case, you should see the overview for the case
To switch to edit-mode, click on the “Edit”-button at the top left
if you see a “ready”-button in the upper left corner you are already in edit-mode

How to create overlays

Select the “view”-button (eye icon) for the series to which you want to add overlays.

Select “Overlays” in the menu on the right
You can now draw a first overlay by clicking on the image in the layer where you want the overlay to be
Every click will place a point connected to the previously placed point, or if clicking on a line between two existing points the point will be placed in between these points
To delete a point click on it and then click the appearing trash can
The default mode is set to “curve”, which means between every point you put down there will be an adjustment point with wich you can modify the curve of the line. Other modes will be explained later
You can give your overlay a label by changing the name in the “Label”-field or clicking on the “Label-description”-button
Then click the “Position”-button and click on the image to choose a position for the label. When you are done click the “Back”-button
If you want to have the overlay in more than one plane, you can either redraw it in the other plane or alternatively go to the plane with the overlay already drawn and copy it to the next/previous plane with the “copy prev”-/”copy next”-button
To change the overlay-color simply click on the Fill- or Stroke-selector or choose one of the presets on the right
Label and overlay-color will be persistent for one overlay across all planes of one series
If you want another overlay describing another finding, click the “Add”-button
You can now switch between the overlays by using the selector at the top
