Beam angle optimization
current status of the clinical use of non-coplanar (nCP)
beams and of
beam angle optimization (BAO):
nCP beams used a lot in cranial SRT and SBRT (liver,
lung), generally without IMRT
Gantry-based units: nCP beams requires couch rotations
time consuming, so preferentially avoided
(Commercial) TPS for BAO + IMRT are generally not
available
little is (and can be) known on the added value of BAO + IMRT
and non-coplanar beams
