Volume Mode
Operation:
1. Press the upper trackball key and move the yellow dots by using the trackball.
Press the upper trackball key again to store the modified contour.
2. Repeat these steps if necessary.
All relevant results (shell contour, volume etc.) are updated automatically.
3. Select the next image plane by using the [Ref ] flip switch control and modify the
contour for this plane.
4. After you have modified the contours in selected image planes, select the [Accept ROI] item.
The result is displayed on the monitor and the VOCAL-Static 3D menu appears in the menu area.
Defining a shell contour (shell geometry)
Shell off
• The outside surface is equal to the generated contours (reference surface geometry).
• The inside surface is represented by an inner point (the inside surface is degenerated).
Selection of other Shell states mean:
Shell inside
• The outside surface is equal to the reference surface geometry.
• The inside surface is the surface geometry of the inner 'parallel' contours with distance Shell
Thickness in mm.
If one of the inside contours is not valid, the inside surface is represented by an inner point (the inside
surface is degenerated). (A contour is only valid if the rotation axis is crossed exactly twice.)
