Your first annotation
Click on a label to activate it. You will see a bar across the top of the image area showing the name and type of the active activation and also a button to inactivate it. All mouse / trackpad functionality works for that active label (instead of the usual scrolling or window / level functionality).
If it’s inactivate, it can’t be drawn or modified. Colored tags show up on the bottom of the image showing the team member who did the annotation. You can also add a note to any individual annotation to indicate special circumstances.
If the annotation uses a
Global label, you’re done and ready to go to the next case.
If the annotation is
Local, you would use your cursor to draw the appropriate annotation. When you are done, you can edit the annotations by grabbing and moving the entire shape, moving individual points, or moving the sides of a bounding box.
When the annotation is to your liking, you can either click inactivate on the bar above the image or just go to the next Image. Saving is automatic.
If you want to do some more editing on an annotation, just click on its tag at the bottom of the image or click + shift on the annotaion itself and it will become active again and available for editing.
Brief Freeform Annotation Video
Mask annotation mode allows multiple shapes to be drawn on the same image. The drawing tool includes pencil width and shape as well as an eraser for corrections. Undo and Redo will remove/reinstate the last drawing or erasing action.
You can zoom, pan, and change the contrast and level using your mouse, trackpad, or with keyboard. Specific instructions are seen by clicking the mouse and keyboard icons in the Navigation column. There are buttons above the image to change the contrast and level values. You can use the preset buttons, keyboard shortcuts for CT scans, or select custom values with the window /level sliders.

Applying the same local label multiple times works the same way. Just click on the same label again to apply the label on the image again.
