Arrow annotation

Draw an arrow and give it a short label.

Browser: available nowmacOS app: 1.4.0 or newer

Press on the point you want to mark and drag towards where the label should sit. The arrow head is drawn where the drag starts. When you release the mouse, a small dialog asks for the label. Type it and select Add arrow, or press Enter.

Cancel, Escape, or a click outside the dialog discards the arrow. An arrow without a label is never created.

To change a label, double-click the arrow.

Arrows and their labels are never written into a DICOM file’s pixel data. Export Viewport State (GSPS) saves them, with the other annotations, in a separate presentation state file; see Export viewport state. Export Image and Export Video draw them onto the picture or clip when Include annotations is ticked, so check a label for patient details before you share the file; see Export image and Export video.
