Tool Body
Required Landmarks
A landmark can be placed or moved while the tool is active. Left-clicking on the limb while a landmark is active will set/relocate it. A landmark becomes inactive when the tool is closed.
Delete a landmark by opening the tool and selecting ‘Delete Landmark’. Deleting a Required Landmark will remove it from the limb, but will still be required to complete this stage.
Optional Landmarks
Optional Landmarks can be selected from the drop-down menu under the Optional Landmarks heading and added by clicking the plus button.
Optional Landmarks have the same functionality as Required Landmarks. Adding Optional Landmarks increases the accuracy of generated suggestions.
Deleting an Optional Landmark will remove the landmark from the limb and its tool from the stage.
Custom Landmarks
Custom Landmarks can be added by typing a name and clicking the plus button. Adding Custom Landmarks will not influence the suggestions generated.
Deleting a Custom Landmark will remove the landmark from the limb. The tool will stay available under the Custom Landmark heading.
How to Use
- Under Required Landmarks, open the Mid Patella Tendon (MPT) tool.
- Place the landmark on the limb by left-clicking on the MPT location on the scan. Left-clicking on a different location on the limb will move the marker to the new location.
- If the scan has a physical marker, use the slide bar to increase the red selection area and click ‘Smooth Marker’. This will replace the physical marker with a digital one. (optional)
- Repeat steps 1 and 2 for Distal Tibia.
- Add additional landmarks by choosing an Optional Landmark from the drop-down menu and clicking the plus button. This will add a corresponding tool for the selected landmark under the Optional Landmark heading. To set the new landmark, repeat steps 1 and 2 with the added landmark tool open. (optional)
- Add a custom landmark by typing a name and clicking the plus button. This will add a corresponding tool for the selected landmark under the Custom Landmark title. Repeat steps 1 and 2 for the added tool. Landmark can be deleted, but the Custom Landmark tool will stay available. (optional)
