SBRT 2016

RTTs role in treatment

• Patient positioning • IGRT-protocols:

– Orthogonal kV images – CBCT (PTV match) – ExacTrac (bone match)

• Motion Management • Online intrafraction monitoring – Real-time Positioning Management (RPM) – ExacTrac – Auto Beam Hold package • Offline intrafraction monitoring – Continuous acquired kV-images during treatment (3fps- 15fps) • In between and possible at the end of the arcs : CBCT (depends on tumorsite)
