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…)
