•
reducing random uncertainties can change the slope of the
dose-response relationship observed in a patient cohort
➢
Online image-based treatment delivery verification (reduce time
between treatment simulation and treatment)
➢
Advanced in vivo treatment dose verification
•
reduction of large systematic uncertainties should be a goal
for OAR and target structures
➢
Contouring uncertainties
➢
Large dose calculation uncertainties (see Luc‘s presentation on
clinical outcome vs. dose calculation algorithm)
➢
Systematic OAR filling changes during treatment (filling
protocols!)
