2017_IGRT course book

Take home message:

IGRT for whole breast (+/- nodes)

•Imaging only in the beam direction will underestimate the

set up error

•No clear benefit of CBCT in terms of accuracy for “robust”

techniques (3D tangents)



but other considerations: workflow? SIB? IMRT?

•Surface image has interesting potential and properties (no

dose) but shouldn’t be the only modality for set-up (rotations,

DIBH…)
