SBRT Treatment Planning: Practical Considerations

For Spine Cases:
IMRT or VMAT is required to create concave dose
distributions.
We use two full RapidArcs, or two partial RapidArcs to avoid
shoulders or arms, one arc with collimator at 0, the other with
collimator at 90.
Multiple fixed IMRT fields can be used.
No need to do any non-coplanar beams (no clearance
anyway).
