SBRT Treatment Planning: Practical Considerations

SBRT CT simulation
• For upper thoracic regions, both arms (elbows)
should be over the patient’s head and included
in the CT scan so that clearance of beams can
be visualized during planning.
• Scan 15 cm beyond field borders (sometimes
non-coplanar beams are needed).
• For spine cases, include sacrum for lower spine
or include C1 for upper spine so that vertebrae
can be easily identified.
