Annotations are a feature of cases and allow important features on images to be annotated and linked to the text in the findings.

The ability to create an annotation is available when in "Edit text and annotations" mode for a case.

To create a new annotation:

  1. go to the image you want to annotate

  2. select the text you want to link to the annotation

  3. click the arrow-plus icon in the toolbar

  4. reposition and rotate the annotation as desired

  5. reposition and change the caption as desired

An annotation can include more than one arrow, which is useful to outline a larger mass or structure, or multiple similar lesions. To do this, select the first arrow and click the two-arrow button in the radial menu. This will create a second arrow that will belong to the same annotation.

Similarly, you can propagate an annotation over multiple slices using up and down icons in the radial menu. When doing so, you should choose one of the arrows to the "key"; this will determine which slice the stack will jump to when the text-link is clicked.

To delete the whole annotation, you can use the arrow-x icon in the toolbar. You can delete individual arrows using the trashcan icon in the radial menu. Deleting the last arrow will delete the annotation.

The standard required for a well annotated case:
