Lung SBRT: target definition and motion management
AAPM TG-101, 2010
ITV definition across the breathing cycle, 4D-CT motion assessment, and when an internal target margin can safely replace gating or tracking.
Site: Lung
Central and ultracentral lung tumours
UK SABR Consortium, 2019
Fractionation options for proximity to the proximal bronchial tree and mediastinal structures, with the constraint sets that separate central from ultracentral risk.
Site: Lung
Liver SBRT
HyTEC, 2021
Mean liver dose and critical-volume constraints by baseline hepatic function, with the fractionation ranges the evidence actually supports.
Site: Liver
Spine SBRT
HyTEC, 2021
Spinal cord and cauda equina constraints by fractionation, contouring conventions for the epidural space, and re-irradiation considerations.
Site: Spine
Pancreas SBRT
NRG / RTOG protocols
Duodenal and bowel constraints under ablative fractionation, and the motion-management steps published trials required for eligibility.
Site: Pancreas
Prostate SBRT fractionation
NRG / RTOG protocols
Rectal and bladder constraints across the commonly used five-fraction regimens, and where they diverge between published protocols.
Site: Prostate
