3D Patient Adjustments

Similar to the Lumi Web application, the Lumi HL2 application allows you to manually adjust 3D models. You can use this function to reshape a 3D model and improve segmentation inaccuracies. This standalone feature can be used on every 3D model.

Use the following steps to visualize a 3D model together with the scan and refine the outline of a 3D model:

1. Select the 3D model you want to shape edit in the 3D patient menu

2. In the submenu, go to More Options
3. Select the Shape Edit tab​

4. ​Use the plier tool to drag the outline of the 3D model to the desired position, a red point will appear​

5. Repeat this for a few points per slice

6. Press 'Apply' if you are satisfied with the changes

7. Repeat steps 1-4 for a few scan slices in coronal, sagittal and axial directions

8. Use the following functions if needed:

   • Add points: drag the outline of the 3D model to a desired location​

   • Remove points: remove a point

   • Sensitivity slider: use the slider to adjust the sensitivity of the outline change. Small value: only a small part of the outline changes. Large value: a large part of the outline changes

   • x0.1: slow movement of the outline of the 3D model. This function is enabled by default and allows for more controlled outline changes

   • Undo: undo your latest change

   • Apply: apply your shape edit changes to the 3D model

9. Save the 3D patient with your shape edited 3D model​

• Note: The total shape is edited with this method, not only the outline on the selected​ scan slice. ​
