1. Press this button to run the automatic balloon boundaries detection algorithm on the
Baseline Anatomy images (see Figure 6-6).
2. Yellow arcs will appear on all Axial Baseline Anatomy images that include a rectal wall drawing.
3. Review the results to verify correct marking of the balloon boundary arcs on all Axial Baseline
Anatomy slices.
4. Where needed, correct the balloon boundary arc by changing its radius (clicking the arc handle and
dragging it) or by displacing the arc (click the arc itself and drag it).
5. Balloon boundary arcs cannot be deleted.
6. To revert the balloon boundaries to the originally detected locations, press this button again.
The automatic balloon boundaries detection should be performed only after the Baseline
Anatomy scans were executed and once the rectal wall has been drawn, as the detection
algorithm uses the rectal wall drawing as input.

◼ The Automatic Balloon Boundaries Detection algorithm can only assist the operator
in marking the balloon boundaries. Therefore, after running this feature, pay strict
attention and review all the Axial Baseline Anatomy images to ensure accurate
identification.
◼ After each run of this feature, you must review the computation results.
